[MJAVADOC-826] - Don't try to modify project source roots by oehme · Pull Request #358 · apache/maven-javadoc-plugin (original) (raw)

The aggregate javadoc mojo was calling addAll directly on the list returned by project.getCompileSourceRoots. This bug was silently ignored by Maven 3, but results in an UnsupportedOperationException on Maven 4.

Do a defensive copy instead.

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 [MJAVADOC-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MJAVADOC-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 basic checks pass. A more thorough check will
  be performed on your pull request automatically.
