Re: [tycho-user] Building patched feature from updatesite 
Looks like a bug in eclipse-repository packaging type and/or p2 code
behind it. I used eclipse-feature with deployableFeature=true and it
works fine. Oddly enough, we do have an integration test to cover
inclusion of patch features in eclipse-repository [1]. Don't have the
time to investigate this now. Sorry.

To clarify my situation, the scenario is as follows:

* An updatesite (in my case http://localhost/core/release/R2_1_0) already exists and contains the feature myplatform.core.feature at version 2.1.0.CR2_1_0
* A new maven project uses this updatesite along with a set of changed plugins to build a patched feature of myplatform.core.feature.
* The patched feature shall be published on a new updatesite (i.e. http://localhost/core/delta-release/R2_1_1) which can be referenced by other projects again.

The goal is to have a delta feature containing only the changed plugins of my latest stable core release.
Newer projects can use both updatesites afterwards to access the latest changed plugins as well.

For test purposes I've created an equivalent test example (building an empty patch feature of org.eclipse.pde at version 3.7.2.v20120120-1420-7b7rFUOFEx2Xnqafnpz0E--0) running into the same troubles.
Obviously, it's possible to build the patched feature, but the updatesite (core.delta.repository) fails. There is a requirement to the org.eclipse.pde of version 0.0.0 (I expected 3.7.2.v20120120-1420-7b7rFUOFEx2Xnqafnpz0E--0 as assigned in my patched feature.xml). The output of my '/core.delta> mvn clean package' can be found in stdout.txt.

Toni

I never had the chance to investigate this, but it is not possible to include both a patch feature and the feature being patch in the same repository [1]. Building patch feature itself should "just work". If this does not work for you, we'll need a small standalone example project to help you troubleshoot the problem.

Hello

I like to create an updatesite containing a feature patch with
tycho/maven. I have an own updatesite containing the feature to patch.
However, it tells me the feature I'd like to patch could not be found
when building a new updatesite:

My patch feature requires the feature to patch in version 2.1.0.  How
can I download the feature to patch from my updatesite automatically
(without installation) so it can be found?

I've added the updatesite to my repositories in parent pom.xml:
