Mercurial ChangeSet In OSGi Bundle MANIFEST with Maven

Question

I am trying to get the Mercurial changeSet and changeSetDate set in my MANIFEST.MF file of OSGi bundle using Maven.

I have added the buldnumber-maven-plugin into my pom.xml:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>buildnumber-maven-plugin</artifactId>
    <version>1.0</version>
    <executions>
        <execution>
            <phase>validate</phase>
            <goals>
                <goal>hgchangeset</goal>
            </goals>
        </execution>
    </executions>
    <configuration>
        <doCheck>false</doCheck>
        <doUpdate>true</doUpdate>
    </configuration>
</plugin>

And my bundle plugin looks like this:

<plugin>
    <groupId>org.apache.felix</groupId>
    <artifactId>maven-bundle-plugin</artifactId>
    <version>2.3.7</version>
    <extensions>true</extensions>
    <configuration>
        <archive>
            <manifestEntries>
                <Build-Change-Set>${changeSet}</Build-Change-Set>
                <Build-Change-Set-Date>${changeSetDate}</Build-Change-Set-Date>
                <Build-Location>${basedir}</Build-Location>
                <Build-Machine>${env.COMPUTERNAME}</Build-Machine>
                <Build-Date>${maven.build.timestamp}</Build-Date>
            </manifestEntries>
        </archive>
        <instructions>
            <!-- All imports, exports, etc... -->
        </instructions>
    </configuration>
</plugin>

When I am executing install goal I see that Maven outputs:

[INFO] --- buildnumber-maven-plugin:1.0:hgchangeset (default) @ esb-security ---
[INFO] Setting Mercurial Changeset: 6524595b0389+
[INFO] Setting Mercurial Changeset Date: 2012-09-05 11:38 +0100

But in my MANIFEST.MF I get:

Build-Change-Set: ${changeSet}
Build-Change-Set-Date: ${changeSetDate}

It does not include the values of change set and change set data. Maybe someone know where might be the problem?

Doesn't anybody know where might be the problem? I'm stuck on this. Please help. — Paulius Matulionis, Sep 06 '12 at 08:52
Have you run this with debug output enabled? Does anything come up there? — Björn Pollex, Sep 06 '12 at 11:57
No. I nothing related to the problem. I see that maven prints changeset and changeset date correctly but in final manifest I am getting: Build-Change-Set: ${changeSet} Build-Change-Set-Date: ${changeSetDate} — Paulius Matulionis, Oct 09 '12 at 16:06

Unless maven-bundle-plugin explicitly supports expression variables like ${changeSet}, etc, they won't be resolved by Maven before this plugin execution. So, you may have to use a separate execution of manifest task bound before process-resources phase, and then use Maven's resource filtering support to post-process generated manifest and substitute those variables set by the maven-bundle-plugin.

Can you provide any example how to do that? – Paulius Matulionis Oct 11 '12 at 10:37

Perhaps if you change the phase for the hgchangeset goal to "initialize" it will occur prior to the Manifest file creation?

Alternatively you can create a stub MF file in your resources folder and use filtering to do the variable substitution, although felix should be able to do this for you.
