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.
