[News.eclipse.foundation] Re: How to use the External Jars In plugin pro

[Ed Merks <merks@xxxxxxxxxx>]

Lincoln,

Please use the newcomers or platform newsgroup for technical questions.  
This newsgroup is for questions about the operations of the Eclipse 
foundation itself.

When developing plugins, you should never modify the classpath directly 
the way you have done.  You should always edit the MANIFEST.MF to add 
dependencies on other plugins.  Modifying the classpath directly will 
fix your build problems but then exactly the same issue will surface 
later as a runtime problem.  If you need external jars, you must put 
them into some plugin and make it part of the runtime for that plugin 
(again by editing the MANIFEST.MF's runtime).
