Re: [equinox-dev] How can I embed a JAR in a plugin?

[David Leangen <osgi@xxxxxxxxxxx>]

Thanks, Alex!

I've been meaning to try out bnd for a while now... I didn't realise
that it could so easily turn an existing jar into a bundle. Sounds very
useful! I'll give that a try and compare results.


In any case, regarding what I did manually, I forgot to mention that I
did of course export each of the packages. Here's the manifest I used:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: net.leangen.expedition.lucene
Bundle-SymbolicName: net.leangen.expedition.lucene
Bundle-Version: 1.0.0
Bundle-Localization: plugin
Bundle-ClassPath: .,lib/lucene-core-2.0.0
Export-Package: net.leangen.expedition.lucene;version="1.0.0",
 org.apache.lucene;version="2.0.0",
 org.apache.lucene.analysis;version="2.0.0",
 org.apache.lucene.analysis.standard;version="2.0.0",
 org.apache.lucene.document;version="2.0.0",
 org.apache.lucene.index;version="2.0.0",
 org.apache.lucene.queryParser;version="2.0.0",
 org.apache.lucene.search;version="2.0.0",
 org.apache.lucene.search.spans;version="2.0.0",
 org.apache.lucene.store;version="2.0.0",
 org.apache.lucene.util;version="2.0.0"



Cheers!
Dave
