3.1.5 compatibility issue?

Well hopefully someone here will have an idea. I'm using Netbeans 6.1 with the Maven plugin 3.1.5. I'm also working on JCAPS applications, while developing some functionality in independent jar files (hence the need for the Maven plugin). However, since installing the plugin, I am not able to open my JCAPS projects (some simple test JCAPS6 apps, and a couple of real JCAPS5.1.3 apps taht have been imported. I get an "Initializing project..." message that never goes away. After disabling the plugin I am able to open the projects.

I have the plugin configured to use an external maven (2.0.8). Is the plugin somehow imcompatible with JCAPS?

Thanks,
Dave Derry
