I have written an application that use a third party library. I have then packaged this as an executable jar using the maven-assembly-plugin (producing a jar with all dependencies including some of the third-party jars).

Next I need to add this jar to a PDE project so it can be launched from eclipse. But to make this work I need to add some of the thirs-party dependencies to my PDE project which is already located in the packaged jar. So I get duplicated dependencies. Any ideas on how to avoid this? Or suggestion to documentation that describes how this is done properly?
