Re: [tycho-user] Tests are not running after upgrading from tycho 0.20 t

[Alex Blewitt <alex.blewitt@xxxxxxxxx>]

This is a known bug in the eclipse repository because there is an OTDT which attempts to patch JDT. If you build a dependency onto JDT as a feature it will try and install OTDT. 

We have a mirror of the main eclipse repository that filters out OTDT for the problems it causes. If you depend on an explicit version of JDT with an exact match or depend on a feature like SDK that has an explicit version match then the problem goes away. 

This is really a P2 problem rather than a Tycho one though — you'd see the same in a non tycho build. The reason you're seeing it now is that Tycho has an upgraded version of P2 and subtle differences (and remote repository content) can change between versions.

Hello,

 

I am doing “mvn clean install” on this repository: https://github.com/deep-modeling/melanee-core . With version 0.20 everything works fine. After upgrading to version 0.21 I get the following errors:

My pom.xml looks like described in the New & Noteworthy section of version 0.21. Here it is (https://github.com/deep-modeling/melanee-core/blob/master/tests/org.melanee.core.tests.plm/pom.xml):

Are there any advices on how to solve/debug this problem?
