[scala-tools] Re: [maven-and-scala] Scala compiler plugins and Eclipse workspace resolution

Sorry if this is the wrong place to report: I don't know enough about
Maven's internals to know if this is more of an issue for m2eclipse,
maven or maven-scala-plugin.

When using a scala compiler plugin described in the POM, and both the
project being built and the scala compiler plug-in are in the same
Eclipse workspace, and M2Eclipse is doing workspace resolution, I get
the following error when M2Eclipse is doing building.

It seems the Maven-scala-plugin assumes the resolved plug-in is a jar,
but it's actually a folder.
