Hi Barry,
Glad there's some hopeful progress.
I didn't use a pom for JenaUsers (Maven and I don't get along so I avoid
it in cases where it doesn't buy me anything) it was just a bndtools
project. The bnd.bnd file (mostly autogenerated) was:
[[[
-runbundles: osgi.cmpn,\
org.apache.felix.shell,\
org.apache.felix.shell.tui,\
com.hp.hpl.jena.core.osgi;version=2.6.4
-runfw: org.eclipse.osgi;version=3.6.1
-buildpath: osgi.core,\
osgi.cmpn,\
biz.aQute.bnd.annotation,\
junit.osgi,\
com.hp.hpl.jena.core.osgi;version=2.6.4
Private-Package: com.epimorphics.support,\
resources
Require-Bundle: com.hp.hpl.jena.core.osgi
Bundle-Activator: com.epimorphics.support.JenaTest
]]]
I believe you could use that from a pom via something like:
[[[
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<version>2.3.4</version>
<dependencies>
<dependency>
<groupId>biz.aQute</groupId>
<artifactId>bndlib</artifactId>
<version>1.43.0</version>
</dependency>
</dependencies>
<extensions>true</extensions>
<configuration>
<instructions>
<_include>bnd.bnd</_include>
</instructions>
</configuration>
</plugin>
]]]
