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

[Cristiano Gavião <cvgaviao@xxxxxxxxx>]

Hi,

I have a p2 project where I concentrate all pom-first bundles that I 
use. I have create features that group those bundle properly. So my 
other projects just need to point to this p2 without have to deal with 
maven dependencies at all.

Now I'm facing a situation where I need to work with two different 
versions of the same feature/bundles, because old projects still will be 
using the old feature( with its bundles)...

So I've created a new feature project (with different ID) and added the 
new bundles to it and fixed the version on the feature.xml. Each has its 
maven dependencies set properly for its own bundle version.

But I can't make it work because to make tycho find those bundles I 
explicitly need to declare dependencies of those bundles in the 
<dependencyManagement> of the main pom.

When I declare two  dependencies maven complains:

> [WARNING]
> [WARNING] Some problems were encountered while building the effective

> 'dependencies.dependency.(groupId:artifactId:type:classifier)' must be 
> unique: com.vaadin:vaadin:jar -> version 7.0.0.alpha1 vs 6.7.4 @ line 
> 109, column 15

And tycho can't found the second bundle...

Could someone give me some clue how could I manage this such use case ?

thanks and regards,
