Build Identifier: Attached is a simple Tycho 0.11.0 project. We'd like to use the tycho-versions-plugin 0.13.0 to change the version. However, the 0.13.0 version of the plugin can't handle older Tycho versions. Version 0.11.0 works fine. Command line: mvn org.sonatype.tycho:tycho-versions-plugin:0.11.0:set-version -DnewVersion=1.2.3 Build result: Build succeeds. Version 0.13.0 produces a ClassNotFoundException. Command line: mvn org.eclipse.tycho:tycho-versions-plugin:0.13.0:set-version -DnewVersion=1.2.3 Build result: [INFO] --- tycho-versions-plugin:0.13.0:set-version (default-cli) @ test.artifact ---

Created attachment 207015 [details] Simple Tycho 0.11.0 test project
I can imagine technical limitations why this doesn't work, but I agree that it really should work... I don't think that we will be able to fix this for 0.13.0, but we shouldn't get the same problem for 0.13.0 projects and the 0.14.0 versions plug-in.
We've analyzed the problem: The tycho-maven-plugin 0.11.0 build extension contains an "extension.xml" descriptor. This descriptor defines which packages and artifacts are exported. The artifacts are only indicated with artifactId, but not with groupId. If you call the tycho-version-plugin:0.13.0 on a project that uses the 0.11.0 build extension, all artifacts from the extension are filtered from the plugin's realm. Matching is done only on artifactId. Example: The tycho-version-plugin has a dependency to org.eclipse.tycho:tycho-metadata-model:0.13.0, but this dependency is filtered because it matches "tycho-metadata-model". So the plugin only "sees" the old org.sonatype.tycho artifacts. This leads to NoClassDefFoundErrors because packages have also been renamed. The solution would have been to specify groupIds in the extension.xml descriptor: <extension> ... <exportedArtifacts> <exportedArtifact>org.sonatype.tycho:tycho-metadata-model</exportedArtifact> ... </exportedArtifacts> </extension> The current extension.xml should be fixed so that the problem can't reappear. The tycho-versions-plugin could be fixed with a custom ClassLoader. We'll evaluate that and propose a patch, if applicable.
Quite honestly, I don't think providing backwards compatibility with tycho 0.11 and earlier is required, especially if it requires non-trivial changes to tycho. Either migrate to tycho 0.13 or use versions plugin from tycho 0.11.
Created attachment 207088 [details] Bugfix and version compatibility test. The patch fixes the exported artifacts of the tycho-maven-plugin build extension. A test ensures that future versions of the tycho-versions-plugin will remain compatible to Tycho 0.12.0 projects.
