When using "bundle" packaging with maven-bundle-plugin goals are executed twice

I have a (simple) maven project with packaging type "bundle" using org.apache.felix:maven-bundle-plugin:2.5.4. It produces a correct OSGI bundle jar. However i observe that all goals are executed at least twice. How do i prevent this? Problem is that some goals (checkstyle in this example) are slow so duplicate execution is a problem here.

NOTE: I use maven 3.2.5 from the command line.

Output or mvn clean install (removed all irrelevant info). Notice that many plugins are executed 4 times. maven-checkstyle-plugin is execurted twice.

UPDATE: This is a known bug (also see answer K Erlandsson): https://issues.apache.org/jira/browse/FELIX-4882

This issue is resolved now (maven-bundle-plugin-2.5.5)

Solution

  • Edit: As rmuller have updated in the question, it is a bug: https://issues.apache.org/jira/browse/FELIX-4882. The bug is fixed in version 3.0.0.

    I recall us having a similar problem (specifically, the bundle was deployed twice) when we upgraded maven-bundle-plugin to 2.5.4. We downgraded it to 2.5.3 to solve our problems.

    I have not dug deeper to see if this is a bug or if there are just other requirements for configuration for 2.5.4.
