Re: [tycho-user] exception resolving target

["Sievers, Jan" <jan.sievers@xxxxxxx>]

we used to see these ClassCastExceptions when you inadvertently configured two different tycho versions in one reactor [1].
this should be detected with a clear error message since tycho 0.16.0 though.

Subject: [tycho-user] exception resolving target

Hi, 
When I run my pom.xml on my local machine the dependency resolving an build works nicely. 
When I run it with Jenkins, I get an exception. The Mvn version is the same on both machines. 

Could this error be related to the content of the target itself or is this somethingelse
? (I list part of the .target below).
