Xtend pulls in JDT - why? [message #667021]

Hello,

I'm trying to reduce the size and complexity of a product that uses
Xtend and Xpand (using an embedded generator, the WorkflowRunner is
called programmatically), and I've run into the following issue. The
feature org.eclipse.xtend requires the feature org.xtend.typesystem.emf
that in turn contains the plug-ins org.xtend.typesystem.emf and
org.xtend.typesystem.emf.ui. (BTW, I didn't find it very helpful that a
non-.ui-feature contains a .ui-plug-in). The plug-in
org.xtend.typesystem.emf.ui now requires org.eclipse.jdt.core and
org.eclipse.emf.converter, amongst others. The .converter plug-in then
pulls in the emf.codegen plug-ins that in turn again require large parts
of the JDT. I end up with a rather messed up product (100 MB zipped
file) that contains parts of the JDT that appear in various locations.
At the moment, I'm trying to work around this by creating my own feature
that contains the Xtend and Xpand plug-ins, but that's less than
optimal. Is there any chance to remove the JDT dependencies or at least
make them optional?

Thanks
Volker

You of course don't need the *.ui bundles.
Ignoring the features and just use the bundles should solve your problem.
Also feel free to file a bugzilla regarding the bad composition of features.
