I'm attempting a Jetspeed portal build (not from source) and have
encountered an exception. I've included snipped maven build output,

org.apache.maven.usability.MojoExecutionExceptionDiagnoser exception.
I can't find any meaningful documentation about the exception on
either Apache's Maven or Jetspeed sites. Anyone have any suggestions
about
what may be wrong
or pointers to useful references?
Maven-2 can be a little difficult to figure out when something goes
wrong. Recommend reading the "book". I have a copy of the Maven-2
online book, a free download from Sonatype:
It used to be available here:
http://www.sonatype.com/book/
But I don't see it there now, weird.
I'm following the Jetexpress tutorial portal documentation and have
found a few other problems in the tutorial documentation. I'd be happy
to assist with updating the documentation, but I'm unsure who to
approach regarding this. Again, any suggestions would be welcome.
Please create a JIRA issue for any bugs you find in the tutorial

Hmmm, that is cryptic.
Which version of Maven are you using? Try upgrading to the latest
version.
