Re: [tycho-user] Packaging type for EMF standalone (CLI) app?
|
not sure if I got your scenario right.
If what you have are bundles with nested jars: get rid of the nested jars by inlining them into the bundle jar.
Nested jars are legacy from pre-eclipse 3.0 days and can cause various problems down the line [1].
