+└───────────────────────────────────────────────────────────────┘
+```
+
+### Service Client Responsibilities
+
+The `javaServiceClient` (`service_client.go:27-45`) is the main interface for analyzing Java code:
+
+**Key Components**:
+```go
+type javaServiceClient struct {
+ rpc provider.RPCClient // JSON-RPC to JDTLS
+ cancelFunc context.CancelFunc // Cancel function for cleanup
+ config provider.InitConfig // Configuration
+ log logr.Logger // Logger instance
+ cmd *exec.Cmd // JDTLS process
+ bundles []string // OSGi bundles for JDTLS
+ workspace string // Workspace directory
+ isLocationBinary bool // Whether analyzing binary artifact
+ globalSettings string // Global settings file path
+ includedPaths []string // Paths to include in analysis
+ cleanExplodedBins []string // Binary explosion dirs to clean up
+ disableMavenSearch bool // Whether to disable Maven lookups
+ activeRPCCalls sync.WaitGroup // Tracks active RPC calls
+ depsLocationCache map[string]int // Cache for dependency locations
+ buildTool bldtool.BuildTool // Reference to build tool
+ mvnIndexPath string // Maven index for labeling
+ mvnSettingsFile string // Maven settings file
+}
+```
+
+**Note**: As of commit 7b864b5, `depsCache`, `depsMutex`, and `depsErrCache` fields have been removed. Dependency caching is now handled by the BuildTool implementations.
+
+**Key Methods**:
+
+1. **Evaluate()** (`service_client.go:49+`)
+ - Evaluates rule conditions using JDTLS
+ - Calls `GetAllSymbols()` to query code
+ - Filters results based on location type (inheritance, method calls, etc.)
+
+2. **GetDependencies()** (via BuildTool)
+ - Returns dependency DAG for the project
+ - Delegates to BuildTool which handles caching internally
+
+3. **GetAllSymbols()** (`service_client.go:111+`)
+ - Sends workspace/executeCommand to JDTLS
+ - Command: `io.konveyor.tackle.ruleEntry`
+ - Returns matching symbols from codebase
+
+### Dependency Caching and Retrieval
+
+The service client in `dependency.go` provides a simplified interface for dependency retrieval. Caching is now handled internally by the BuildTool implementations.
+
+**Key Methods**:
+
+1. **`GetDependencies(ctx context.Context)`** - Returns flattened dependency list
+ - Calls `GetDependenciesDAG()` internally
+ - Converts DAG structure to flat list
+ - Uses `provider.ConvertDagItemsToList()` for transitive dependencies
+
+2. **`GetDependenciesDAG(ctx context.Context)`** - Returns dependency DAG
+ - **Simplified**: No longer manages cache or synchronization at this level
+ - Directly delegates to `buildTool.GetDependencies(ctx)`
+ - BuildTool handles all caching and thread-safety internally
+
+**Simplified Retrieval Flow**:
+```
+┌──────────────────────────────────────────────┐
+│ User requests dependency analysis │
+└──────────────┬───────────────────────────────┘
+ │
+ v
+┌──────────────────────────────────────────────┐
+│ Service Client: GetDependenciesDAG() │
+│ - No locks needed at this level │
+└──────────────┬───────────────────────────────┘
+ │
+ v
+┌──────────────────────────────────────────────┐
+│ BuildTool: GetDependencies(ctx) │
+│ - BuildTool manages its own cache/locks │
+│ - For Maven/Gradle: uses depCache │
+│ - For Binary: uses resolveSync │
+└──────────────┬───────────────────────────────┘
+ │
+ v
+┌──────────────────────────────────────────────┐
+│ Return map[uri.URI][]provider.DepDAGItem │
+│ - Key: Build file URI │
+│ - Value: List of dependencies with DAG │
+└──────────────────────────────────────────────┘
+```
+
+**Architectural Benefits of Refactoring**:
+- **Separation of concerns**: Service client no longer manages caching
+- **Encapsulation**: Each BuildTool controls its own synchronization strategy
+- **Reduced complexity**: Eliminated `depsMutex`, `depsCache`, and `depsErrCache` from service client
+- **Consistent behavior**: All build tools use same depCache pattern
+- **Thread-safety**: Moved from service client level to BuildTool level where it belongs
+
+**Dual Interface**:
+- `GetDependencies()`: Returns flat list (`[]*provider.Dep`)
+- `GetDependenciesDAG()`: Returns DAG structure (`[]provider.DepDAGItem`)
+- Both delegate to BuildTool's internal implementation
+- DAG structure preserves transitive dependency relationships

+## Usage Guide
+
+### How to Use BuildTool
+
+#### Example: Getting Dependencies
+
+```go
+import (
+ "context"
+ "github.com/konveyor/analyzer-lsp/external-providers/java-external-provider/pkg/java_external_provider/bldtool"
+ "github.com/konveyor/analyzer-lsp/provider"
+)
+
+// Create BuildTool options
+opts := bldtool.BuildToolOptions{
+ Config: provider.InitConfig{
+ Location: "/path/to/project", // Project directory
+ },
+ MvnSettingsFile: "/path/to/settings.xml", // Optional
+ MvnInsecure: false,
+ DisableMavenSearch: false,
+ Labeler: myLabeler, // For identifying open source deps
+}
+
+// Get appropriate build tool
+buildTool := bldtool.GetBuildTool(opts, logger)
+if buildTool == nil {
+ // No build file found (no pom.xml or build.gradle)
+ return
+}
+
+// Get dependencies
+ctx := context.Background()
+deps, err := buildTool.GetDependencies(ctx)
+if err != nil {
+ // Handle error
+}
+
+// deps is a map[uri.URI][]provider.DepDAGItem
+// Key: URI of build file (pom.xml or build.gradle)
+// Value: Dependency DAG with direct and transitive dependencies
+```
+
+#### Example: Resolving Sources
+
+```go
+// Check if we need to resolve sources
+if buildTool.ShouldResolve() {
+ // Get resolver
+ resolver, err := buildTool.GetResolver("/path/to/fernflower.jar")
+ if err != nil {
+ // Handle error
+ }
+
+ // Resolve sources (download + decompile as needed)
+ srcLocation, depLocation, err := resolver.ResolveSources(ctx)
+ if err != nil {
+ // Handle error
+ }
+
+ // srcLocation: Where source code is located
+ // depLocation: Where dependency JARs are located (e.g., ~/.m2/repository)
+}
+```
+
+### How to Use Dependency Module
+
+#### Example: Decompiling a JAR
+
+```go
+import (
+ "context"
+ "github.com/konveyor/analyzer-lsp/external-providers/java-external-provider/pkg/java_external_provider/dependency"
+)
+
+opts := dependency.DecompilerOpts{
+ DecompileTool: "/path/to/fernflower.jar",
+ log: logger,
+ workers: 10, // Number of concurrent workers
+ labler: myLabeler,
+ disableMavenSearch: false,
+ m2Repo: "/home/user/.m2/repository",
+}
+
+decompiler, err := dependency.getDecompiler(opts)
+if err != nil {
+ // Handle error
+}
+
+// Decompile a JAR as a dependency (creates Maven structure)
+artifacts, err := decompiler.Decompile(ctx, "/path/to/library.jar")
+if err != nil {
+ // Handle error
+}
+
+// artifacts: []JavaArtifact with Maven coordinates
+```
+
+#### Example: Identifying JAR Coordinates
+
+```go
+import (
+ "context"
+ "github.com/konveyor/analyzer-lsp/external-providers/java-external-provider/pkg/java_external_provider/dependency"
+)
+
+// Try to identify Maven coordinates for a JAR
+artifact, err := dependency.ToDependency(ctx, logger, labeler, "/path/to/unknown.jar", false)
+if err != nil {
+ // Could not identify
+}
+
+// artifact.GroupId: "org.example"
+// artifact.ArtifactId: "my-library"
+// artifact.Version: "1.2.3"
+// artifact.FoundOnline: true/false
+```

+
+## Key Design Patterns
+
+### 1. Strategy Pattern (Build Tools)
+
+The `BuildTool` interface allows different build systems to be used interchangeably:
+- `mavenBuildTool` for Maven projects
+- `gradleBuildTool` for Gradle projects
+- `mavenBinaryBuildTool` for binary artifacts
+
+### 2. Factory Pattern
+
+`GetBuildTool()` acts as a factory, automatically selecting the correct build tool implementation based on project structure.
+
+### 3. Worker Pool Pattern
+
+The decompiler uses a worker pool (10 workers by default) to parallelize decompilation:
+- Jobs submitted to a channel
+- Workers pull jobs and process concurrently
+- Results collected via response channel
+
+### 4. Fallback Pattern
+
+Multiple fallback mechanisms ensure robustness:
+- Maven dependency resolution → fallback to pom.xml parsing
+- Maven Central lookup → fallback to embedded POM → fallback to structure inference
+- Plugin execution → fallback to direct command parsing
+
+### 5. Caching Pattern
+
+Build tools cache results to avoid expensive re-execution:
+- Hash build files (pom.xml, build.gradle)
+- Compare hashes on subsequent calls
+- Return cached results if unchanged
+
+---
+
+## Common Use Cases
+
+### 1. Analyzing a Maven Project
+
+```
+User provides: /path/to/maven-project
+
+Flow:
+1. GetBuildTool() finds pom.xml → creates mavenBuildTool
+2. GetDependencies() runs mvn dependency:tree
+3. Parses Maven output into DepDAGItem hierarchy
+4. Returns dependencies to service client
+5. JDTLS uses dependencies for code analysis
+```
+
+### 2. Analyzing a Gradle Project
+
+```
+User provides: /path/to/gradle-project
+
+Flow:
+1. GetBuildTool() finds build.gradle → creates gradleBuildTool
+2. Determines Gradle version and Java compatibility
+3. GetDependencies() runs gradlew dependencies
+4. Parses Gradle tree output
+5. Returns dependencies to service client
+```
+
+### 3. Analyzing a Binary (JAR/WAR/EAR)
+
+```
+User provides: /path/to/application.war
+
+Flow:
+1. GetBuildTool() detects binary → creates mavenBinaryBuildTool
+2. ShouldResolve() returns true
+3. GetResolver() creates binary resolver
+4. ResolveSources() decompiles WAR:
+ - Explodes WAR structure
+ - Finds embedded JARs
+ - Decompiles each JAR
+ - Creates project structure
+5. Returns decompiled source location
+6. JDTLS analyzes decompiled sources
+```
+
+### 4. Full Analysis Mode with Missing Sources
+
+```
+User provides: /path/to/maven-project
+Mode: FullAnalysisMode
+
+Flow:
+1. GetBuildTool() → mavenBuildTool
+2. GetDependencies() → finds all dependencies
+3. GetResolver() → mavenDependencyResolver
+4. ResolveSources():
+ - Runs mvn download sources plugin
+ - Identifies JARs without sources
+ - Decompiles missing JARs in parallel
+ - Stores sources in ~/.m2/repository
+5. JDTLS has access to all dependency sources
+```
+
+---
+
+## Error Handling
+
+### BuildTool Errors
+
+- **No build file found**: Returns `nil` from `GetBuildTool()`
+- **Maven command fails**: Falls back to pom.xml parsing with gopom
+- **Gradle wrapper missing**: Returns error (Gradle wrapper required)
+- **Dependency tree parsing fails**: Returns partial results or error
+
+### Resolver Errors
+
+- **Plugin execution fails**: Returns error (can't proceed without sources)
+- **Decompilation fails**: Individual failures logged, continues with others
+- **Maven Central unavailable**: Cached error prevents repeated attempts
+
+### Artifact Identification Errors
+
+- **All strategies fail**: Returns artifact with partial info (e.g., just artifactId)
+- **Maven Central rate limit**: Falls back to local strategies
+- **Malformed JAR**: Returns error
+
+---
+
+## Performance Considerations
+
+### 1. Caching
+
+- BuildTool caches dependency results using SHA256 hash of build files
+- Maven Central errors cached to prevent repeated API calls
+- Dependency location cache prevents repeated grep operations
+
+### 2. Parallelization
+
+- Decompiler uses 10 workers by default (configurable)
+- Maven/Gradle execution timeouts (5 minutes default)
+- Concurrent decompilation of multiple JARs
+
+### 3. Lazy Resolution
+
+- Sources only resolved when `ShouldResolve()` is true or FullAnalysisMode
+- Binary projects skip dependency tree execution
+- Gradle subproject analysis only when subprojects exist
+
+---
+
+## Extension Points
+
+To add support for a new build system:
+
+1. Implement the `BuildTool` interface
+2. Add detection logic to `GetBuildTool()`
+3. Implement a corresponding `Resolver` if sources need resolution
+4. Update this documentation
+
+Example skeleton:
+
+```go
+type antBuildTool struct {
+ buildFile string
+ // ... other fields
+}
+
+func (a *antBuildTool) GetDependencies(ctx context.Context) (map[uri.URI][]provider.DepDAGItem, error) {
+ // Parse build.xml
+ // Extract dependencies
+ // Return DAG structure
+}
+
+func (a *antBuildTool) GetResolver(decompileTool string) (dependency.Resolver, error) {
+ // Return Ant-specific resolver
+}
+
+// Implement other interface methods...
+```
+
+---
+
+## Troubleshooting
+
+### "No build tool found"
+
+**Cause**: No pom.xml, build.gradle, or binary file detected
+
+**Solution**: Ensure project has proper build file or provide binary artifact
+
+### "Maven dependency resolution failed"
+
+**Cause**: Maven command failed (network issues, invalid pom.xml, etc.)
+
+**Solution**: Check Maven installation, network connectivity, pom.xml validity. Fallback parser may still work.
+
+### "Gradle wrapper not found"
+
+**Cause**: Gradle project without wrapper
+
+**Solution**: Generate Gradle wrapper: `gradle wrapper`
+
+### "Decompilation failed"
+
+**Cause**: FernFlower error, invalid JAR, or missing JAVA_HOME
+
+**Solution**: Verify FernFlower path, JAR validity, and JAVA_HOME environment variable
+
+### "Java version incompatible with Gradle"
+
+**Cause**: Gradle ≤8.14 requires Java 8, but only Java 17+ available
+
+**Solution**: Set JAVA8_HOME environment variable to Java 8 installation

+
+## Conclusion
+
+The bldtool and dependency modules work together to provide a comprehensive solution for analyzing Java projects:
+
+1. **bldtool** detects the build system and extracts dependency information
+2. **dependency** resolves missing sources through download or decompilation
+3. **provider/service client** coordinates these modules with the language server
+
+This architecture enables the Java External Provider to analyze:
+- Source projects (Maven/Gradle)
+- Binary artifacts (JAR/WAR/EAR)
+- Projects with or without dependency sources
+- Multi-module projects
+
+The modular design allows easy extension for new build systems while maintaining a consistent interface for the provider layer.

+// Resolver handles downloading and decompiling dependency sources for different build systems.
+// It ensures that all project dependencies have accessible source code for analysis, either by
+// downloading source JARs from repositories or by decompiling binary JARs using a decompiler.
+//
+// The resolver is obtained from BuildTool.GetResolver() and is automatically invoked during
+// provider initialization when BuildTool.ShouldResolve() returns true or when running in
+// FullAnalysisMode.
+type Resolver interface {
+ // ResolveSources downloads dependency sources and decompiles JARs that lack source artifacts.
+ // This is a critical step for enabling deep code analysis, as it ensures the language server
+ // has access to all dependency source code.
+ //
+ // Process:
+ // 1. Execute build tool command to download available source JARs
+ // 2. Parse output to identify dependencies without sources
+ // 3. Locate binary JARs for unresolved dependencies
+ // 4. Decompile missing sources using a decompiler (parallel worker pool)
+ // 5. Store decompiled sources in appropriate repository structure
+ //
+ // Parameters:
+ // - ctx: Context for cancellation and timeout control (typically 5-10 minute timeout)
+ //
+ // Returns:
+ // - sourceLocation (string): Absolute path to project source directory
+ // For source projects: Original project location
+ // For binary artifacts: Path to generated project directory
+ // - dependencyLocation (string): Absolute path to local dependency repository
+ // May be empty string if the build tool uses a different caching mechanism
+ // - error: Error if source resolution fails
+ //
+ // Example Usage:
+ // resolver, _ := buildTool.GetResolver("/path/to/decompiler.jar")
+ // srcPath, depPath, err := resolver.ResolveSources(ctx)
+ // if err != nil {
+ // // Handle resolution failure
+ // }
+ // // srcPath: Project directory with sources
+ // // depPath: Repository with dependency sources (may be empty)
+ //
+ // Performance Considerations:
+ // - Uses worker pool for parallel decompilation
+ // - Can take several minutes for large projects with many dependencies
+ // - Progress logged at various verbosity levels
+ // - Individual decompilation failures logged but don't stop overall process
+ //
+ // Error Handling:
+ // - Returns error if build tool command fails completely
+ // - Returns error if decompiler initialization fails
+ // - Logs individual JAR decompilation failures but continues
+ // - May cache errors to avoid repeated failures

+# gradle-multi-project-example
+
+Basic gradle template with subprojects, deployable to Heroku as separate dyno processes.
+
+## What's included?
+
+1. Gradle Plugins
+ - application plugin
+ - shadowjar plugin
+2. Code Style
+ - checkstyle
+ - findbugs
+ - pmd
+3. General Libraries
+ - guava
+ - junit
+ - mockito
+ - log4j2 via slf4j
+4. Multi-Project Gradle Setup
+ - see: [settings.gradle](settings.gradle)
+5. Heroku Deployment
+ - see: [Procfile](Procfile), [stage.gradle](gradle/heroku/stage.gradle)
+
+## Development
+
+### Building
+
+```
+$ ./gradlew clean build
+```
+
+### Testing
+
+```
+$ ./gradlew clean test
+```
+
+### Building Deployment Artifacts
+
+```
+$ ./gradlew clean stage
+```
+
+### Running
+
+Use the Gradle [application plugin](https://docs.gradle.org/current/userguide/application_plugin.html).
+However, `./gradlew run` will run applications in lexicographical order.
+Instead, explicitly specify which subproject to run:
+
+```
+$ ./gradlew template-core:run
+$ ./gradlew template-server:run
+```

+# Gradle start up script for POSIX generated by Gradle.
+#
+# Important for running:
+#
+# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+# noncompliant, but you have some other compliant shell such as ksh or
+# bash, then to run this script, type that shell name before the whole
+# command line, like:
+#
+# ksh Gradle
+#
+# Busybox and similar reduced shells will NOT work, because this script
+# requires all of these POSIX shell features:
+# * functions;
+# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+# * compound commands having a testable exit status, especially «case»;
+# * various built-in commands including «command», «set», and «ulimit».
+#
+# Important for patching:
+#
+# (2) This script targets any POSIX shell, so it avoids extensions provided
+# by Bash, Ksh, etc; in particular arrays are avoided.
+#
+# The "traditional" practice of packing multiple parameters into a
+# space-separated string is a well documented source of bugs and security
+# problems, so this is (mostly) avoided, by progressively accumulating
+# options in "$@", and eventually passing that to Java.
+#
+# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
+# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
+# see the in-line comments for details.
+#
+# There are tweaks for specific operating systems such as AIX, CygWin,
+# Darwin, MinGW, and NonStop.
+#
+# (3) This script is generated from the Groovy template
+# https://github.com/gradle/gradle/blob/HEAD/platforms/jvm/plugins-application/src/main/resources/org/gradle/api/internal/plugins/unixStartScript.txt
+# within the Gradle project.

+# gradle-multi-project-example
+
+Basic gradle template with subprojects, deployable to Heroku as separate dyno processes.
+
+## What's included?
+
+1. Gradle Plugins
+ - application plugin
+ - shadowjar plugin
+2. Code Style
+ - checkstyle
+ - findbugs
+ - pmd
+3. General Libraries
+ - guava
+ - junit
+ - mockito
+ - log4j2 via slf4j
+4. Multi-Project Gradle Setup
+ - see: [settings.gradle](settings.gradle)
+5. Heroku Deployment
+ - see: [Procfile](Procfile), [stage.gradle](gradle/heroku/stage.gradle)
+
+## Development
+
+### Building
+
+```
+$ ./gradlew clean build
+```
+
+### Testing
+
+```
+$ ./gradlew clean test
+```
+
+### Building Deployment Artifacts
+
+```
+$ ./gradlew clean stage
+```
+
+### Running
+
+Use the Gradle [application plugin](https://docs.gradle.org/current/userguide/application_plugin.html).
+However, `./gradlew run` will run applications in lexicographical order.
+Instead, explicitly specify which subproject to run:
+
+```
+$ ./gradlew template-core:run
+$ ./gradlew template-server:run
+```
