I have some OSGi artifacts (Eclipse plugins) built using Tycho. Then I have some other project building a Debian package with those artifacts included (own MOJO). The OSGi artifacts are declared as simple POM dependencies in the Debian package project POM.

Everything worked well until now, when I switched from Tycho 1.7.0 to 2.7.5. I have to switch because I need some other feature ("wrapAsBundle"). In the dependency resolution phase there are now some artifacts not found in the repository (own hosted Artifactory) and the build fails. It seems strange that there is something *.eclipse-plugin pulled which does not exist in the repository.

• 1 Note that the current version of Tycho is 4.0.10 – greg-449 Commented Nov 16, 2024 at 12:17
• Yes, but my projects are on Java 11. – Martin Commented Nov 16, 2024 at 12:21
• If I change the packaging of the related OSGi artifacts to 'jar' the everything in the debian project is resolved. However, then project dependency resolution fails. It must be something about changes with the packaging type and resolver. – Martin Commented Nov 16, 2024 at 12:48
• Seems related: github/eclipse-tycho/tycho/issues/2005 – Martin Commented Nov 16, 2024 at 13:13
• 2 The fact that your projects are on Java 11 should not prevent you from using the latest Tycho version. – howlger Commented Nov 16, 2024 at 16:51

It seems this is fixed starting from Tycho 3.0.x: https://github/eclipse-tycho/tycho/pull/2011/commits/fdd9a7f09667106783048d61898d5d0091437975

replaceTypeWithExtension needs to be set to true then.
