Description

When building NPanday against a released version (e.g. trunk -> 1.3-incubating), there is a problem generating Mojos.

The .NET-based Plugins we release should reference NPanday.Plugin.dll from the reactor using ${project.version} - in the current case 1.3.1-incubating-SNAPSHOT. But then the MojoGenerator is used from the bootstrap-version (1.3-incubating). This one also references (is compiled against) NPanday.Plugin of 1.3-incubating.

Now, since NPanday.Plugin is strong-named the "old" MojoGenerator reflects on the "new" .NET-based Mojos and runs into a version conflict.

In order to fix this, we have to relax the versioning in MojoGenerator by listening to AppDomain.AssemblyResolve event and help finding the right version.

I'm not sure if we can "downgrade" the version for the Plugin reference, or if we need to load the newer NPanday.Plugin into the AppDomain and use that instead.
