Hi Wim, 

The signing maven plugin is not found in repo1. This is expected since this 
plugin is only available in eclipse's nexus : http://maven.eclipse.org/nexus/  

If this worked before this could mean that (these are only ideas): 
   - There have been a change in the global settings.xml on hudson. Eclipse 
repository was used as a mirror for all repository, and it was configured to be 
more selective.
   - We are using a shared $HOME/.m2/repository and another build had already 
downloaded the plugin for us. But this repo has been cleared.

Try to add 
http://maven.eclipse.org/nexus/content/repositories/milestone-indigo/   as a 
pluginRepository in our pom. This could work.
