I just tried a fresh download and install and wasn't able to recreate the odd behavior: I think Steven Wu and Dima was in the process of trying it out as well; perhaps we could see what their experience has been as well.

Also, Eclipse will turn it off for all projects, so I'd have to turn it on and off all the time (because I don't only work on cTAKES, obviously). > Otherwise perhaps a post to UIMA's Users forum? I'm not sure what I'd ask. What we're doing right now (using <execute/> in the lifecycle mapping for exec-maven-plugin) is strongly discouraged by m2e: http://wiki.eclipse.org/M2E_plugin_execution_not_covered#execute_plugin_goal And it's guaranteed to run JCasGen on all java executions: http://stackoverflow.com/questions/6691723/m2e-generated-code-with-exec-maven-plugin So we know we're doing it wrong, and I'm getting exactly the behavior m2e promises when we do that. ;-) If people are opposed to doing it the way m2e suggests (writing a jcasgen-maven-plugin and a connector, as is done in my patch), then I think the only alternative would be to use <ignore/> instead of <execute/> so that JCasGen never runs in Eclipse.
