If the target platform contains a feature and a feature patch for that feature, the build fails. Example: - Feature A contains org.eclipse.core.runtime in version 3.4 - Feature patch B (for feature A) updates the version of the included org.eclipse.core.runtime to version 3.5 The build fails when I try to include both feature A and feature patch B in a feature built by Tycho. The reason for the failure seems to be, that the p2 dependency resolver excludes 3.4 from the target platform (because it is not needed with the patch present), but then Tycho dependency walker code fails. Apparently the dependency walker code is not available of feature patches. I remember that I had once proposed a patch to remove the depencency walker usage in case of the p2 resolver [1]. It is not really needed, and if it fixes this issue, I'll probably apply the patch. Related issues: - TYCHO-580 [2] is a different issue. I only tried to include a feature patch built elsewhere. TYCHO-580 is about building patches with Tycho. - TYCHO-228 [3] looks like the same issue. Since we now track bugs here, TYCHO-228 should be closed as duplicate.

FYI, there is a separate issue with building feature patches using tycho. I have local branch against 0.11.1, but need to port it for 0.13 before I can apply.

AFAIK this is TYCHO-580. If you plan to fix this issue, please open a new bug here in Bugzilla so that we will be able to generate the release notes for 0.13.0 from Bugzilla.
Created attachment 197086 [details] ITest demonstrating the issue This integration test demonstrates the problem. The build results in the following message: java.lang.RuntimeException: Could not resolve plugin org.eclipse.core.runtime_3.4.0.v20080512; Path to dependency: eclipse-feature:featurePatch.external.combine.feature:1.0.0.qualifier: org.eclipse.tycho.core.osgitools.DefaultReactorProject@24561250 eclipse-feature:org.eclipse.example.original_feature:1.0.0: C:\Users\D051585\.m2\repository\p2\org\eclipse\update\feature\org.eclipse.example.original_feature\1.0.0\org.eclipse.example.original_feature-1.0.0.jar at org.eclipse.tycho.core.ArtifactDependencyVisitor.newRuntimeException(ArtifactDependencyVisitor.java:42) at org.eclipse.tycho.core.ArtifactDependencyVisitor.missingPlugin(ArtifactDependencyVisitor.java:33) at org.eclipse.tycho.core.osgitools.AbstractArtifactDependencyWalker.traversePlugin(AbstractArtifactDependencyWalker.java:207) at org.eclipse.tycho.core.osgitools.AbstractArtifactDependencyWalker.traverseFeature(AbstractArtifactDependencyWalker.java:85) at org.eclipse.tycho.core.osgitools.AbstractArtifactDependencyWalker.traverseFeature(AbstractArtifactDependencyWalker.java:170) at org.eclipse.tycho.core.osgitools.AbstractArtifactDependencyWalker.traverseFeature(AbstractArtifactDependencyWalker.java:89) at org.eclipse.tycho.core.osgitools.AbstractArtifactDependencyWalker.traverseFeature(AbstractArtifactDependencyWalker.java:170) at org.eclipse.tycho.core.osgitools.EclipseRepositoryProject$1.walk(EclipseRepositoryProject.java:60) at org.eclipse.tycho.core.osgitools.AbstractArtifactBasedProject.resolve(AbstractArtifactBasedProject.java:42) at org.eclipse.tycho.core.resolver.DefaultTychoDependencyResolver.resolveProject(DefaultTychoDependencyResolver.java:101) at org.eclipse.tycho.core.maven.TychoMavenLifecycleParticipant.afterProjectsRead(TychoMavenLifecycleParticipant.java:91) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:268) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:151) ... 11 more

Btw, I found git log more reliable/convenient way to generate release notes.
