Maven BND plugin and building WAR files with dependencies
Hi,
I'm using the Maven BND plugin to generate the manifest for a WAR file
that contains embedded dependencies. I have tried to follow all the
guidelines out there (OPS4J+Apache websites), but without luck.
The main problem seems to be that the plugin cannot recognize where the
embedded dependencies are. My POM BND instructions look like this:
<Export-Package>
... exported packages *from embedded dependencies* goes here...
... exported packages from WAR project goes here ...
</Export-Package>
<Bundle-ClassPath>.,WEB-INF/classes</Bundle-ClassPath>
<Embed-Directory>WEB-INF/lib/</Embed-Directory>
... more instructions ...
When I run Maven on this it generates warnings like this:
[WARNING] Warning in manifest for
se.streamsource.streamflow:streamflow-web:war:1.1-SNAPSHOT : No sub JAR
or directory WEB-INF/classes
[WARNING] Warning in manifest for
se.streamsource.streamflow:streamflow-web:war:1.1-SNAPSHOT : No sub JAR
or directory WEB-INF/lib/somedependency.jar
... and so on with one warning line for each embedded jar ...
The resulting WAR has the correct WEB-INF/lib with all the jar files,
the BundleClasspath header *is correct* (with all WEB-INF/lib
dependencies added to it), but the ExportPackage header is wrong as it
does not include the packages from the dependencies that I want to
export. Funnily enough, the corresponding ImportPackage header *is
correct*, i.e. it includes imports of the packages I wanted to export!
Am I doing something wrong here, or is the BND plugin not able to handle
WAR files with embedded dependencies properly yet?
thanks, Rickard

Sorry for such a stupid recommendation which has nothing to do with packaging.

Thanks for the tip, but I'm afraid we have pretty already given up on
the setup as a whole. We're simply out of time, and can't get it to
build (the Maven BND issue) nor deploy consistently (the hanging + other
Glassfish deploy issues). As I said, I would LOVE for this to work, but
it DOESN'T, and I'm just out of breath and time.
Which means we have to either roll our own (yuck), do plugins through
REST API's, or skip plugins entirely. I don't like any of the options,
but such is life.

Just an FYI, certain errors during framework startup can be problematic
when the framework shutdown hook is enabled. You can disable the
shutdown hook with felix.shutdown.hook=true in conf/config.properties.
Not sure if that is what you are seeing, but you can try and see if it
helps you to avoid the hang.

Yeah, but it seems I'd have to replace "painful" with "impossible".
It's so sad. On paper doing webapps as bundles looks like an awesome
alternative, as we can do jar sharing and functionality plugins easily
through OSGi. In practice, using GlassFish/Felix+BND it has proven to be
very tough, to the point where I'm close to giving up on the whole
thing. GlassFish routinely hangs during deployment so I have to "kill
-9" it, and Maven BND cannot package my WAR file, as outlined. So I
can't build it, and I can't run it. Theory - awesome, Practice - hell.
Maybe I just have to wait a couple of years, until theory and practice
are more aligned.

Packaging war file with BND is a pain full process. Try Spring DM web extender.

Yes, but I have . included:

So that's not it.
I tried downloading the sample bundle from the OPS4J page
(http://wiki.ops4j.org/display/ops4j/Getting+the+benefits+of+maven-bundle-plugin+in+other+project+types),
and when I run "mvn install" it actually has the same warning messages,
so it's not just me it seems. The difference from that sample is that I
want to export a package in an embedded jar, which doesn't work, as the
plugin doesn't seem to recognize the jar files properly when using the
<Embed-Directory>WEB-INF/lib/</Embed-Directory> instruction.
