Maven + OSGI

[Peter Horlock <pe...@googlemail.com>]

Hi,


I have a question regarding Maven dependency management and the OSGi-based
BIRT Report Engine (RE).

The RE, in order to be available at runtime in the tomcat environment,
must conform to a specific directory structure: 'top-level' JARs in
WEB-INF/lib, config.ini in WEB-INF/platform/configuration and dozens of
further JARs with horribly detailed filenames in
WEB-INF/platform/plugins and sub-directories.

How do I combine MVN storage of the RE JARs (and other files -
config.ini, MANIFEST.MF, ...) with the strict directory structure
requirements at deployment time? Ideally, I'd also like to automatically
upload the RE to the Maven repo initially.

I've found a hopeful plugin under
http://mvn-dp-plugin.sourceforge.net/site/plugin-info.html, but the
documentation is scanty and I do not know if it will do what I need...


Thanks in advance,

Peter

Hi Peter,

Unfortunately I don't have an assembly configuration I can share at the
moment - I use Pax-Runner to deploy my apps.
If you're still stuck perhaps you could send a note to general@ops4j.org as
there are a lot of OSGi users on that list.

Could anyone please share his/her assembly plugin settings and assembly file
for OSGI?

Thanks in advance,

Could you please send me your assembly plugin settings?

Thanks in advance,

I'm sure there are several people here using OSGi + Maven (me for one)

however, this doesn't sound like a general OSGi issue as such, because OSGi
doesn't actually mandate a
specific layout of bundles - instead your layout is specific to Equinox, the
OSGi framework used by Eclipse
(and therefore BIRT which is an Eclipse project)

you could perhaps look into using the headless Eclipse/PDE build, but this
can be painful to use - IMHO the
best (and simplest) option is just use the assembly plugin to arrange
everything

What about the plugin I found:

well that plugin generates standard OSGi deployment packages:


http://www.osgi.org/javadoc/r4v41/org/osgi/service/deploymentadmin/DeploymentPackage.html

which are a way to atomically install and update a collection of bundles,
managed by the deployment
admin bundle (so you need this installed) - while you can use this to deploy
apps onto a framework
it won't help you do the initial bootstrapping, so you'd still need to mimic
some of the Equinox layout

another option might be to use pax-runner to generate the Equinox layout:

   http://issues.ops4j.org/browse/PAXRUNNER-177
   http://paxrunner.ops4j.org/space/Pax+Runner

but I still think using the assembly plugin would be simplest approach
initially

Thanks,

No one here using OSGI + Maven?
What about the plugin I found:

Could that do the trick?

The assembly plugin would work with the proper configuration, I'd
assume. But it does sound painful.
