What code base are you working off? git clone of the MOA repo?
Does the code base contain any modified code changes that may have
triggered this error? The exec-maven-plugin instances in MOA's pom.xml
files use 1.6.0 of the plugin, not 3.0.0.
What maven command did you issue from the terminal and in what directory?
Cheers, Peter
