Re: [tycho-user] Modifying manifest.mf during 'generate-resources' phase

[David Aldridge <daldridge@xxxxxxxxx>]

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

      <plugin>

        <groupId>${tycho-groupId}</groupId>

        <artifactId>tycho-packaging-plugin</artifactId>

        <version>${tycho-version}</version>

        <configuration>

          <archive>

            <manifestFile>${project.build.directory}/whatever/output/dir/MANIFEST.MF</manifestFile>

          </archive>

        </configuration>

        <goals>

          <goal>jar</goal>

        </goals>

      </plugin>

...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 ${project.build.directory} (where any pre-existing manifest gets copied to as part of packaging), it appears it gets overwritten with the pre-existing manifest.mf file (I'm guessing as part of the 'prepare-package' phase).

I can't seem to get manifest.mf 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?

David,

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