Uses constraint violation - org.slf4j.api vs. slf4j.api

    Details

      Description

      Latest bit of rpm madness...

      This conflict occurred:

      org.osgi.framework.BundleException: Could not resolve module: org.eclipse.m2e.wtp.jpa [931]
        Bundle was not resolved because of a uses contraint violation.

      	at org.eclipse.osgi.framework.eventmgr.EventManager$EventThread.run(EventManager.java:340)

      So, since slf4j.api is installed via 5 upstream projects (5 symlinks, actually, to rh-java-common):

      $➔ find . -name "*slf4j.api*jar" -exec ls -l {} \;
      lrwxrwxrwx 1 root root 81 Oct 11 13:00 ./share/eclipse/droplets/jgit/eclipse/plugins/slf4j.api_1.7.4.jar -> ../../../../../../../../../rh-java-common/root/usr/share/java/slf4j/slf4j-api.jar
      lrwxrwxrwx 1 root root 81 Oct 12 05:19 ./share/eclipse/droplets/linuxtools-docker/eclipse/plugins/slf4j.api_1.7.4.jar -> ../../../../../../../../../rh-java-common/root/usr/share/java/slf4j/slf4j-api.jar
      lrwxrwxrwx 1 root root 81 Oct 11 14:46 ./share/eclipse/droplets/egit-egit/eclipse/plugins/slf4j.api_1.7.4.jar -> ../../../../../../../../../rh-java-common/root/usr/share/java/slf4j/slf4j-api.jar
      lrwxrwxrwx 1 root root 75 Oct 21 09:58 ./share/eclipse/droplets/mylyn-versions-git/eclipse/plugins/slf4j.api_1.7.4.jar -> ../../../../../../../../../rh-java-common/root/usr/share/java/slf4j/api.jar
      lrwxrwxrwx 1 root root 81 Oct 11 14:46 ./share/eclipse/droplets/egit-mylyn/eclipse/plugins/slf4j.api_1.7.4.jar -> ../../../../../../../../../rh-java-common/root/usr/share/java/slf4j/slf4j-api.jar
      

      ... I removed it from the RPM in favour of the other bundle, which was already installed into the fedora/rhel eclipse.

      BUT... since this RH SCL rh-java-common slf4j-api.jar exports a different, incompatible bundle name:

      Bundle-SymbolicName: slf4j.api

      than the one in devstudio's update site / target platform

      Bundle-SymbolicName: org.slf4j.api

      NOW, I'm getting this:

      org.osgi.framework.BundleException: Could not resolve module: org.eclipse.m2e.wtp.jpa [931]
                      Unresolved requirement: Require-Bundle: org.slf4j.api; bundle-version="1.6.2"
      

      Snjezana got this too in m2e.core:

      BundleException: Could not resolve module: org.eclipse.m2e.core.ui [866]
        Unresolved requirement: Require-Bundle: org.eclipse.m2e.maven.runtime; bundle-version="[1.7.0,1.8.0)"
          -> Bundle-SymbolicName: org.eclipse.m2e.maven.runtime; bundle-version="1.7.0.20160603-1931"; singleton:="false"
             org.eclipse.m2e.maven.runtime [876]
               Unresolved requirement: Require-Bundle: org.slf4j.api; bundle-version="1.6.2"

      So... not sure what to do to solve this.

      I suppose the best case would be for the m2e and w2e-wtp bundles to depend on the slf4j.api PACKAGES instead of BUNDLES, so that they can run on the fedora/rhel versions instead of those from the devstudio update site / target platform.
