I tried submitting to their official JIRA board but I have no permission to do so:

https://ops4j1.jira.com/browse/PAXEXAM/fixforversion/12880/?selectedTab=com.atlassian.jira.jira-projects-plugin:version-issues-panel

Can someone expert help me with my problem? I am at the end of my ropes already :(

Sample Project(If the project file does not work just tell me):

command: mvn clean verify

Thanks

Answer 1

Looks like you're having conflicting versions of the OSGi Core API on your class path. At runtime, your OSGi framework (Felix or Equinox) should be the only Core API on the classpath.

If you have some other version like org.osgi:org.osgi.core as a (transitive) dependency, make sure to give it provided scope or to exclude the dependency.
