Mysterious exception
Hi,
I'm attempting to build an apache project (jetspeed) using maven. The build
throws a org.apache.maven.usability.MojoExecutionExceptionDiagnoser
exception. The exception has no meaningful documentation nor does it appear
on the maven mailing lists.
Can anyone suggest what may have caused the exception?
Here's a snipped copy of the build output:
$ mvn -e -P tomcat,min
+ Error stacktraces are turned on.

Send your question to the Jetspeed Users (or Developers) email list,
since it is their project that you are trying to build and running
into problems with.
