Yeah, it looks like we need to improve the validation of descriptors. None of the assembly mojos should really work without an assembly id.
Would you mind filing an issue at: http://jira.codehaus.org/browse/MASSEMBLY? That way, you can watch/vote for the issue, and see when it gets corrected. Also, if you're binding the assembly plugin into your build lifecycle for a project, you might want to consider using assembly:single, since it doesn't force a forked execution of the project's build. It will be a little more performant for you most likely. -john On Fri, Apr 11, 2008 at 12:44 PM, Harper, Brad <[EMAIL PROTECTED]> wrote: > Ah, thanks. > > I've since found that "mvn assembly:attached" works, both from the > command line and when run as part of a maven build lifecycle [with the > same assembly descriptor.] > > Is the assembly id being inferred or derived from the project then, when > running the 'attached' goal? > > I suggest that the error message be improved for this use case, at the > least.
