Re: [tycho-user] How could I work with 2 different versions of the same

[Cristiano Gavião <cvgaviao@xxxxxxxxx>]

Well,

I've removed the p2 project from the reactor and interestingly all 
bundles and features have been built properly... including the both 
features containing the bundles with different versions that is not 
working with the p2 project...

So, that the problem is related to P2 repository project...

In some last trial, when I remove one of the two features from the p2 
category, the build runs ok...

I will try to create a example project reproducing this problem next 
weekend...

regards

Cristiano
