  • Thread-topic: [tycho-dev] Tycho 2.7.1 is released


I am trying to update the builds of the APP4MC project to use 2.7.1. Most builds work fine, but I now see a SLF4J warning on start when loading the repositories saying that there is no binding. I do not see this info with 2.7.0.
I have a SLF4J binding in my target platform, so I assume this message comes from Tycho itself. Not sure how this could be solved then.

In one project I now I get the following error:

	Execution default-package-feature of goal org.eclipse.tycho:tycho-packaging-plugin:2.7.1:package-feature failed: Neither raw version nor format was specified: null

Unfortunately there is no additional information. And that error did not appear with 2.7.0. If this is an additional check that was added, it would be good to know what actually is wrong so I can fix it in the project.

I suppose the issue results from this fix:

And I suppose the error comes up because the feature.xml in the project that fails now contained entries like this:

      <import plugin="org.eclipse.ui" match="compatible"/>

I think such entries existed because of mistakes in the past and nobody noticed that. The entry obviously is incorrect, because, what should it match? 
But even if I update the feature.xml and remove those incorrect entries, the build still fails. I am only running "mvn clean verify", so my local repository is clean.

When running with verbose output I only see the following exception:

Caused by: java.lang.IllegalArgumentException: Neither raw version nor format was specified: null

    at org.eclipse.tycho.packaging.PackageFeatureMojo.execute (

Any idea what I could do to fix this? Or is this some regression?

Mit freundlichen Grüßen / Best regards
