There're plenty of bugs and feature requests for the JUnit Archiver (and related stuff). This functionality stills inside the Jenkins Core.

In addition, the xUnit Plugin mostly replaces the publisher functionality, but it depends from hudson.tasks.junit internals.

Proposals:

• Move JUnit to a separate plugin
• Mark the JUnit Publisher as "deprecated" in the documentation
• Move test suites to test-harness and test-acceptance projects
