Context
I have a maven project uses many dependencies. I want to use this project as an OSGI bundle. This bundle have to export all its package and dependencies packages, and includes the physical jars.
My first approach was to use apache Felix, maven-copy-dependency and maven-eclipse-plugin.
- apache felix maven-bundle-plugin for MANIFEST.MF building (including dependencies export)
- maven-dependency-plugin for jars copy
- maven-eclipse-plugin for eclipse files update (.classpath and .project)
- maven-clean-plugin for deleting temporary files.
I finally leave this approch because I could not managed to set up maven plugins producing the result targeted.
At the end my solution was :
- apache felix maven-bundle-plugin for MANIFEST.MF building (including dependencies export)
- maven-dependency-plugin for jars copy
- specific maven plugin for files update (.classpath)
- maven-clean-plugin for deleting temporary files.
This solution produces :
- a MANISFEST.MF including export package for all maven dependencies
- a jar including jar dependencies
- an eclipse .classpath including all copied dependencies
