fixes #4

Fixes #4: e.g. "mvn" and "mvn -Prun-its clean install" now work again.

I do not know if this is the right way to fix this.

There are also further issues with the build like these properties:

<localTestSrc>${user.dir}/FindBugs/findbugsTestCases/src</localTestSrc>
<remoteTestSrc>scm:svn:https://codenarc.svn.sourceforge.net/svnroot/codenarc/tags/0.17/src/test/</remoteTestSrc>

which seem out of date.

btw: Thanks for creating this plugin. :) Keep up the good work. :)
