Richard van der Hoff commented on MJAR-40:
------------------------------------------
Hrm, it seems I got this wrong in the case where the project doesn't have any
dependencies; it's a long story, but basically the indexing code tries to open
{{target/classes}} as a zip file, and fails.
The list returned by {{project.getRuntimeClasspathElements()}} includes
{{target/classes}}; it's incorrect to add this as a ConfiguredIndexJar to the
archiver.
I can't really be doing with preparing a patch for this - if you don't have any
dependencies, you can disable the 'Class-Path' in the manifest, which works
around the bug.

> When creating a jar with an index, and a 'Class-Path' in the manifest, the

> The attachment contains a testcase which demonstrates a ClassCastException in
> the plexus-archiver; a fix to that, and a fix to the maven-archiver to make
> it actually use the fixed code.
