Locate Java dependencies using maven metadata

[jayvdb]

There are at least two Java dependencies where the Fedora and Ubuntu packages provide maven metadata that could be used to find the jar files

• pmd : https://github.com/coala/coala-bears/issues/804
• checkstyle : https://github.com/coala/coala-bears/issues/1250 (https://github.com/coala/coala-bears/issues/626) We probably need a new MavenRequirement in http://gitlab.com/coala/package_manager/ , which then needs to be used by the bears implemented in Java.

https://repo.maven.apache.org/maven2/net/sourceforge/pmd/pmd/5.0.1/pmd-5.0.1.jar 

or we can use suitable version if we wish for

Please tell me the use of install_command( ). Does it installs the package or returns a string displaying how to install the package? I am a bit confused.

I've created https://gitlab.com/coala/package_manager/issues/13 for MavenRequirement.

You may need to do a quick PR like https://github.com/coala/coala-bears/pull/1300 , to bring in the latest coala, or you could include a commit like that in your PR for this or for https://github.com/coala/coala-bears/issues/1250.
