Error starting bundle in karaf: “via two dependency chains”

Question

I am currenty developing a camel route which reads from a netty4/mllp endpoint and store the hl7 message to a amqp queue.

This is my environment:

apache-maven-3.3.9
apache-karaf-4.1.1
apache-camel-2.18.3
apache-artemis-2.0.0

this is my pom.xml

I can run the project in eclipse with a "main" class with no problem. But when I am deploying the bundle to the Karaf container I am experiencing some issues.

I am generating the bundle jar, with the previus pom.xml file, with the apache felix plugin, maven clean package goal.

The karaf installation is a clean one. I have only setup the following:

the artemis amqp broker inside the same karaf container

feature:repo-add artemis feature:install artemis-amqp

the camel components

feature:repo-add camel feature:install camel-core camel-netty4 camel-amqp camel-hl7

I copy the jar bundle into the deploy folder and try to start it with bundle:start my-bundle but I get the following error.

Error executing command: Error executing command on bundles:
Error starting bundle 110: Unable to resolve demograficos-bundle [110](R 110.0): missing requirement [demograficos-bundle [110](R 110.0)] osgi.wiring.package; (&(osgi.wiring.package=javax.jms)(version>=1.1.0)(!(version>=2.0.0))) Unresolved requirements: [[demograficos-bundle [110](R 110.0)] osgi.wiring.package; (&(osgi.wiring.package=javax.jms)(version>=1.1.0)(!(version>=2.0.0)))]

I understand from this that the jms implementation is missing from the container.

I tried feature:install jms, but now I got the following error

Error executing command: Error executing command on bundles:
        Error starting bundle 110: Uses constraint violation. Unable to resolve resource demograficos-bundle [demograficos-bundle [110](R 110.0)] because it is exposed to package 'javax.jms' from resources org.apache.geronimo.specs.geronimo-jms_1.1_spec [org.apache.geronimo.specs.geronimo-jms_1.1_spec [120](R 120.0)] and org.apache.geronimo.specs.geronimo-jms_2.0_spec [org.apache.geronimo.specs.geronimo-jms_2.0_spec [75](R 75.0)] via two dependency chains.

Chain 1:
  demograficos-bundle [demograficos-bundle [110](R 110.0)]
    import: (&(osgi.wiring.package=javax.jms)(version>=1.1.0)(!(version>=2.0.0)))
     |

  org.apache.geronimo.specs.geronimo-jms_1.1_spec [org.apache.geronimo.specs.geronimo-jms_1.1_spec [120](R 120.0)]

Chain 2:
  demograficos-bundle [demograficos-bundle [110](R 110.0)]
    import: (&(osgi.wiring.package=org.apache.camel.component.amqp)(version>=2.18.0)(!(version>=3.0.0)))
     |
    export: osgi.wiring.package=org.apache.camel.component.amqp; uses:=javax.jms

But I can't see the two previus geronimo bundles listed, only one

WARNING: multiple bundles are exporting package javax.jms

- org.apache.geronimo.specs.geronimo-jms_1.1_spec [122]

I am really having some troubles understanding how jar/bundle versions work together under karaf.

Any ideas? maybe I should change the felix plugin in the pom.xml

Looks like you declared your own bundle exporting the javax.jms package to be in version 1.1, while Artemis depends on a bundle exporting javax.jms in version 2.0, make sure you also depend on a version 2.0 javax.jms version (as that's the version used by artemis) and your issue will be gone.
