compilation errors

I can't compile the project. Tried the following:

1. import maven project from Intellij. Got these errors:
   a. package.org.apache.commons.io does not exist
   b. cannot find symbol
   symbol: variable IOUtils
   location: class jp.eisbahn.oauth2.server.spi.servlet.TokenServlet

2. running "mvn clean package" from command line. Got same errors

Do you know how can I solve it?
