Hey,

 

I’m trying out Neon RC1 as target and am hitting a kind of strange uses conflict I cannot figure out. It looks like this:

 

!ENTRY com.wamas.platform.rest 4 0 2016-05-20 08:02:35.086

!MESSAGE FrameworkEvent ERROR

!STACK 0

org.osgi.framework.BundleException: Could not resolve module: com.wamas.platform.rest [41]

  Bundle was not resolved because of a uses contraint violation.

  org.osgi.service.resolver.ResolutionException: Uses constraint violation. Unable to resolve resource com.wamas.platform.rest [osgi.identity; osgi.identity="com.wamas.platform.rest"; type="osgi.bundle"; version:Version="5.5.3.qualifier"; singleton:="true"] because it is exposed to package 'javax.annotation' from resources org.eclipse.osgi [osgi.identity; osgi.identity="org.eclipse.osgi"; type="osgi.bundle"; version:Version="3.11.0.v20160427-2120"; singleton:="true"] and javax.annotation [osgi.identity; osgi.identity="javax.annotation"; type="osgi.bundle"; version:Version="1.2.0.v201602091430"] via two dependency chains.

 

Chain 1:

  com.wamas.platform.rest [osgi.identity; osgi.identity="com.wamas.platform.rest"; type="osgi.bundle"; version:Version="5.5.3.qualifier"; singleton:="true"]

    require: (osgi.wiring.bundle=org.eclipse.core.runtime)

     |

    provide: osgi.wiring.bundle: org.eclipse.core.runtime

  org.eclipse.osgi [osgi.identity; osgi.identity="org.eclipse.osgi"; type="osgi.bundle"; version:Version="3.11.0.v20160427-2120"; singleton:="true"]

 

Chain 2:

  com.wamas.platform.rest [osgi.identity; osgi.identity="com.wamas.platform.rest"; type="osgi.bundle"; version:Version="5.5.3.qualifier"; singleton:="true"]

    require: (&(osgi.wiring.bundle=org.glassfish.jersey.media.jersey-media-json-jackson)(bundle-version>=2.22.2))

     |

    provide: osgi.wiring.bundle; bundle-version:Version="2.22.2"; osgi.wiring.bundle="org.glassfish.jersey.media.jersey-media-json-jackson"

  org.glassfish.jersey.media.jersey-media-json-jackson [osgi.identity; osgi.identity="org.glassfish.jersey.media.jersey-media-json-jackson"; type="osgi.bundle"; version:Version="2.22.2"]

    import: (&(osgi.wiring.package=org.glassfish.jersey.internal.util)(&(version>=2.22.0)(!(version>=3.0.0))))

     |

    export: osgi.wiring.package=org.glassfish.jersey.internal.util; uses:=jersey.repackaged.com.google.common.base

  org.glassfish.jersey.core.jersey-common [osgi.identity; osgi.identity="org.glassfish.jersey.core.jersey-common"; type="osgi.bundle"; version:Version="2.22.2"]

    import: (&(osgi.wiring.package=jersey.repackaged.com.google.common.base)(&(version>=2.22.0)(!(version>=3.0.0))))

     |

    export: osgi.wiring.package=jersey.repackaged.com.google.common.base; uses:=javax.annotation

  org.glassfish.jersey.bundles.repackaged.jersey-guava [osgi.identity; osgi.identity="org.glassfish.jersey.bundles.repackaged.jersey-guava"; type="osgi.bundle"; version:Version="2.22.2"]

    import: (&(osgi.wiring.package=javax.annotation)(&(version>=1.2.0)(!(version>=2.0.0))))

     |

    export: osgi.wiring.package: javax.annotation

  javax.annotation [osgi.identity; osgi.identity="javax.annotation"; type="osgi.bundle"; version:Version="1.2.0.v201602091430"]

       at org.eclipse.osgi.container.Module.start(Module.java:444)

       at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.incStartLevel(ModuleContainer.java:1620)

       at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.incStartLevel(ModuleContainer.java:1599)

       at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.doContainerStartLevel(ModuleContainer.java:1571)

       at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.dispatchEvent(ModuleContainer.java:1514)

       at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.dispatchEvent(ModuleContainer.java:1)

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

 

I can understand chain 2. There /is/ a bundle called javax.annotation that exports javax.annotation (1.2.0). The problem for me is chain 1. It says that my bundle is exposed to javax.annotation from the org.eclipse.osgi bundle, but that bundle has no mention of anything like it. Any Idea what’s happening and how to resolve it?

 

Side note: In this case I’m using Neon as target, but Mars.2 as IDE, if that’d make any difference (don’t think so...) :)

 

Cheers, Thanks in advance,

Markus
