So, one of my guys is taking a look at sonatype's mavenbook example
http://www.sonatype.com/book/simple-project.html where it says to run mvn
install on the killerapp project.
We're seeing this error msg. Has anyone else seen this problem and how did
they solve it. I googled a bit and tried using forkMode to get around this
problem to no avail.
