Using a quick internet search, this might be problem under Windows
with another process still holding onto that file:

NB: I don't use Windows.

There is no need to run then tests each time you build. My IntelliJ IDEA doesn't do this. On the command line, you would add the following option to the mvn command:

-DskipTests=true

I don't use MOA, so I'm not familiar with its algorithms. Your best option is to post on the MOA user mailing list.

Cheers, Peter
