[tycho-user] NPE in EquinoxResolver

[Kai Kreuzer <kai@xxxxxxxxxxx>]

Hi,

I am currently trying to run my Tycho build (with 0.13.0-SNAPSHOT) on  
a hosted Jenkins server (at Cloudbees, see also  
https://cloudbees.zendesk.com/entries/20206657-building-a-maven-tycho-project).
Running it locally, everything works fine, but on the Jenkins server I  
get the following exception:

mavenExecutionResult exceptions not empty

Is this anything known or shall I enter a bug report?
