Hi
I have a mojo that calls the MavenExecutionRequest, and asks it to run
archetyp:create. When I try to run it, the Embedder complains with the
errormessage and stacktrace below. In short, it complains that there is no
field ErrorDiagnostics in DefaultMaven. Why is the Embedder trying to access
the non exsitant field? Has there been a code change that relies on that field
now beeing present in DefaultMaven?
