Can you supply a small sample project that exhibits this problem?

It seems to be triggered by exclusion using excludeRoots.

Empty project with attached pom would trigger the execption.

Jan, thanks for the sample project.

I've reproduced the problem locally and have a fix in the works. In the mean time you can use version 2.6 of the plugin as a work-around.

Thank you, the 2.7.1-SNAPSHOT worked without Exception. The biggest delay was fighting Nexus.

Thanks for the quick fix. For the record my CI builds broke yesterday with this error and I can report that it occurs in version 2.5, 2.6, and 2.7. I did not try any other versions.

Jordan,

This issue only affects 2.7, not any other versions.

Hmmm... perhaps I am using 2.7 without knowing it some how despite having the version set explicitly in my pom. I'll look into that and report back.

You are right, this effects only 2.7. I only had the pmd plugin configured in the reporting section of my pom and not in the build section, thus I was unwittingly using 2.7. Once I sorted this out for good measure I did test with 2.5 and 2.6 and they both work fine. Thanks again for the quick fix and I'll look forward to the next release.

is 2.7.1 released? I have troubles finding the release. The Maven Central http://repo1.maven.org/maven2/ doesn't have it nor does the Apache Releases https://repository.apache.org/content/repositories/releases .

No, but this issue will be fixed with this version once released.
You can see at the Jira versions tab of the plugin when every version was released.
I've deployed a snapshot, you can use https://repository.apache.org/content/repositories/snapshots/ as snapshot-repository to test it.

No, it's not released yet.

There was one other potential regression that was posted on the user list. I want to see that through, before starting the release process.
