Re: [tycho-user] Modifying during 'generate-resources' phase?

I believe you can use the manifestEntries portion of the archive configuration to add additional entries to an existing manifest file.

You can probably avoid using the maven bundle plugin completely and move the instructions into the archive configuration.

Thanks, Simon.  That information indeed got the 'maven-bundle-plugin' executing.  However, I'm still having difficulty getting the generated manifest file packaged.

My first attempt was to include the 'maven-jar-plugin' into the build, and specify the manifest file location that was generated by 'maven-bundle-plugin'.  That didn't work, as the 'eclipse-plugin' packaging uses 'tycho-packaging-plugin' to generate the .JAR, which I'm thinking I need to retain.

I can't see a way to configure 'tycho-packaging-plugin' to grab my generated manifest.  I tried configuring 'tycho-packaging-plugin' with


...but the "archive" configuration for that plugin isn't the typical maven-jar-plugin archive block, but rather some classpath class identifier(?).

Furthermore, if I configure 'maven-bundle-plugin' to generate the manifest to ${} (where any pre-existing manifest gets copied to as part of packaging), it appears it gets overwritten with the pre-existing file (I'm guessing as part of the 'prepare-package' phase).

I can't seem to get generation to occur as part of the 'prepare-package' phase, but after whatever the tycho plugins are doing.  Nor can I get manifest generation to occur as part of the 'package' phase, but before 'tycho-packaging-plugin' generates the .JAR.

Any ideas?

You need to add 'eclipse-plugin' to supportedProjectTypes in the
maven-bundle-plugin configuration. See [1].
