Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MSOURCES-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MSOURCES-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify -Prun-its to make sure integration tests checks pass. A more thorough check will
  be performed on your pull request automatically.

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.

To make clear that you license your contribution under
the Apache License Version 2.0, January 2004

Tests are failing only when they are run together.

The root cause of the problem:

EnhancedCompositeBeanHelper in maven-core is responsible for setting the right values for the mojo properties. In this case, both mojos (SourceJarMojo and TestSourceJarMojo) have the same properties. The helper is reusing an internal cache (ACCESSIBLE_FIELD_CACHE) for both mojos, and therefore for the run of the second mojo, the information of the cache is invalid because the field of the second mojo has to be set to accessible, but this step is skipped because the cache is filled.

In the unit tests, a workaround is to add EnhancedCompositeBeanHelper.clearCaches(); as a cleanup step. In the invoker tests it is not possible.

@gnodet: Is this behavior a bug? Or do you have a hint how to avoid it?
