Build Identifier: 20110916-0149

I have installed m2e 1.0.100 from the Indigo update site and the m2e connector for build-helper-maven-plugin 0.14 from the m2e marketplace. 
Auto-update is enabled in Eclipse and on each search for new updates an error is reported for the "m2e connector for build-helper-maven-plugin". It seems that a new version of the plugin is available (0.15.0) but Eclipse cannot install it due to dependency problems. Here is the detailed error message from the Eclipse update dialog:

Cannot complete the install because of a conflicting dependency.
  Software being installed: m2e connector for build-helper-maven-plugin 0.15.0.201109290002 (org.sonatype.m2e.buildhelper.feature.feature.group 0.15.0.201109290002)

Can you figure out what is the problem here?

Kind regards,
Christof Luick.
