Description Konrad Windszus CLA 2011-03-17 05:34:07 EDT 
If I have a pom file with a packaging "bundle" (using the maven-bundle-plugin), I always get an NPE with 0.12.1. This is the stacktrace:

eclipse.buildId=M20100909-0800
java.version=1.6.0_24
java.vendor=Apple Inc.
BootLoader constants: OS=macosx, ARCH=x86_64, WS=cocoa, NL=de_DE

Command-line arguments:  -os macosx -ws cocoa -arch x86_64 -product org.eclipse.epp.package.jee.product -keyring /Users/kwindszus/.eclipse_keyring -showlocation

Comment 3 Milos Kleint CLA 2011-03-17 05:46:09 EDT 
seems to be related to https://issues.sonatype.org/browse/MNGECLIPSE-2555

could you please try in the Eclipse indigo M5 or upcoming Indigo M6 build?
Comment 4 Konrad Windszus CLA 2011-03-17 06:01:34 EDT 
Seems to be fixed with the latest 0.13 version. Is it possible to work around that problem in 0.12.1 (e.g. by providing a project configurator for bundle plugins)?
Comment 5 Igor Fedorenko CLA 2011-03-17 09:46:36 EDT 
Yes, this is a dup of https://issues.sonatype.org/browse/MNGECLIPSE-2555 and it is fixed in master. There are no plan to backport the fix to 0.12. As a workaround, you can add version to all maven plugins bound to project build lifecycle (via pluginManagemenet, for example).
