Description Paul Tatavu CLA 2011-02-14 16:05:01 EST 
I installed m2e (without the logback configuration bundle) and started it with an empty workspace.  The m2e.core , m2e.core.ui and a few other m2e bundles are activated by default.
Comment 1 Igor Fedorenko CLA 2011-02-14 18:21:16 EST 
I simulated MavenPlugin activation timeout and this revealed that m2e.core bundle activation is triggered by usage data collection plugin. This needs to be addressed by 3.7M6

Avoid early m2e activation

The problem here was that the Usage Data Collector is always activated and instantiates all monitors triggering early activation.

In the patch the monitor I wrote now has no references to m2e.core and instead relies on checking/listening to the bundle activation state before creating the MavenProjectListener.
Comment 3 Pascal Rapicault CLA 2011-02-15 12:51:34 EST 
Patch released.
