@Peter Correct. Problem with being half Gen Y and a Virgo :D

In all seriousness, though, this is the first time that I've a tool be umm... stubborn, if you will.

@Mirko @Peter That extensions looks like it'll do the trick, though. That said, I might wait for DM Server to settle down, and see where OSGi Blueprints go before I get my hands dirty again.

Stuart's suggestion is actually what we are using. Works well enough for us in 99% of our cases. Here is a snippet that should get you started in no time:
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.0.0</version>
<extensions>true</extensions>
<configuration>
<instructions>
<unpackBundle>true</unpackBundle>
<manifestLocation>META-INF</manifestLocation>

<_plugin>aQute.lib.spring.SpringComponent</_plugin>
</instructions>
</configuration>
<executions>
<execution>
<id>bundle-manifest</id>
<phase>process-classes</phase>
<goals>
<goal>manifest</goal>
</goals>
</execution>
</executions>
</plugin>

Read through the documentation to find more tweaks to adjust it to your specific needs.

Cheers,
Mirko

Wow man, you're picky :-) You want to work things out of the box for all your choices! Unfortunately, OSGi is used in many different areas and therefore has no extensive support for a specific configuration like yours.

The easiest solution seems to be Stuart's advice, use the bundle plugin. This is based on bnd.

bnd has a built-in plugin for spring, you can activate it with (I think, I do not use maven):

<_plugins>aQute.lib.spring.SpringComponent</_plugins>

If you have problems with this, let me know. Kind regards,

Peter Kriens

@pat The big reason I didn't go with bundlor was because you had to duplicate project info, and it couldn't even convert the version number (especially if it contains -SNAPSHOT) into an osgi version.

Personally I liked bnd better, and if it could parse spring manifests and maybe supported import-template then that's one thing taken care of.

In this case you should use SpringSource Bundlor w...

In this case you should use SpringSource Bundlor which parses also your XML files ... an in a newer version of BND it has a plugin to parse also your Spring XML stuff ... aQute.lib.spring.SpringComponent

@Mirko:

Yes, I know about OBR, but I don't think DM Server supports provisioning from them at the moment.

Nexus Pro does support it, and some work has been done to get Apache Archiva to support it as well, but again, DM Server does not support either :/

That said, I still think it's a bit redundant having both an OBR and an M2 repo.

I would definitely like to see where these things go, but for now it's "Call me when I can 'maven deploy' to one".

@Mcculls
Yes, I did try maven-bundle-plugin. It gets it about 90% right. Where it mostly falls over is web modules, and it doesn't know about stuff declared in Spring applicationContexts, so it leaves some stuff out.

I had a quick play with pax, but I couldn't figure out how to deploy my project, which is bundles + web modules + dm server in one hit.

I might have to revisit this when I have some more time.

You might also want to look into the OPS4J Pax projects, such as:

http://paxrunner.ops4j.org

and

http://www.ops4j.org/projects/pax/construct/

For example, try:

mvn org.ops4j:maven-pax-plugin:run

2009-10-07T01:27:27.202+10:00

Just as a side note. Did you know that there is a semi official spec under RFC112 (http://www.osgi.org/download/rfc-0112_BundleRepository.pdf) called OBR. Felix maintains it and as far as I know, it supports provisioning from a Nexus (Pro?) repository (via console and probably scripting as well). There is currently a lot of work going on in this direction, so maybe soon we can see a fully official and seamless repository integration. Pascal from the Equinox P2 team is currently working on that I think.
