No, I am quite certain m2e developers have no immediate plans to reimplement eclipse launcher framework or java Process.
I also believe your situation is rather rare if not unique, so most likely developing alternative Maven launcher configuration is your best bet to get the process termination bahaviour you need. And, hey, if your implementation proves to be popular, we can discuss how you can contribute it to m2e core. -- Regards, Igor On 2013-03-07 6:39 AM, David Geiger wrote:
I agree that this issue is not limited to m2e. It appears to me, however, that it effects the usability of m2e on Windows quite heavily. Is this just due to my particular use case, i.e., the appengine-maven-plugin launching a Jetty process, or how do how other people deal with this? In my current setup, any Maven process launched by m2e will never terminate correctly. According to https://bugs.eclipse.org/bugs/show_bug.cgi?id=38016 it seems that the general issue is not going to be fixed unless the Java implementation of the Process.destroy() method on Windows changes. The current 'kill' behavior might also be intended as it guarantees that even non-responding applications are terminated. In that case, the m2e developers might want to provide a dedicated way to terminate Maven gracefully.

Whenever I click on the red terminate button in the Eclipse console view, the Maven process launched by m2e does not seem to terminate correctly. As opposed to launching Maven from the command prompt, it neither displays the "BUILD SUCCESS" message, nor does it terminate any child processes such as the Jetty server launched by appengine-maven-plugin. I need to terminate these left-over processes manually every time I stop a Maven application from within Eclipse. Is there another way to terminate Maven applications using m2e? The issue seems to be related to the behavior of the terminate button in Eclipse. Apparently, this button calls java.lang.Process.destroy(), which, on Windows, is implemented as a simple kill and does not allow applications to exit gracefully.
