[tycho-dev] why can't I access org.osgi.resource package from org.eclips

[Cristiano Gavião <cvgaviao@xxxxxxxxx>]

Hi devs,

I'm developing a plugin to specifically work with tycho based buildings. I

need have access to interfaces of org.osgi.resource package, but I'm not being able to do that and I don't know why.

The annoying thing is that I can access classes from org.osgi.framework. package.

CodeSource srcb = Bundle.class.getProtectionDomain().getCodeSource();
        if (srcb != null) {
          URL jar = srcb.getLocation();
          getLog().info("Bundle loaded from " + jar);
        }

Returns:

Bundle loaded from file:/home/cvgaviao/.m2/repository/org/eclipse/tycho/org.eclipse.osgi/3.10.0.v20140606-1445/org.eclipse.osgi-3.10.0.v20
140606-1445.jar

But when I tried this:

CodeSource srcr = Resource.class.getProtectionDomain().getCodeSource();
        if (srcr != null) {
            URL jar = srcr.getLocation();
            getLog().info("Resource loaded from " + jar);
        }

gives me an exception:  A required class was missing while executing o.l.t.m.rx:o.l.t.m.rx.plugin:0.2.1-SNAPSHOT:generateIndex: org/osgi/resource/Resource

could someone give a light here, please ?

thanks,

Cristiano
