NoClassDefFoundError when running a JUnit Plug-in Test [message #270526]

I have two plug-in projects. The first (lets call it "com.foo") is a simple
plug-in I've written to get the hang of writting plug-ins. The second is a
JUnit Plug-in (let's call it "com.foo.test") that's written as a JUnit
Plug-in test for the com.foo Plug-in. I can successfully run the the com.foo
plug-in manually using a Run-time workbench, but when I try to test it using
the com.foo.test JUnit Plug-in (by running it as a "JUnit Plug-in Test"), I
get a NoClassDefFoundError for any and all of the classes defined in my
com.foo Plug-in. The com.foo.test code compiles fine, it just can't find the
com.foo classes at run-time.

I'm running in the 3.0 environment and I defined the com.foo.test JUnit
Plug-in to depend on the com.foo plug-in.

Why might my com.foo plug-in's classes not be found when running in the
"JUnit Plug-in Test" environment?

This is something I found recently. I'm not sure whether it solves your
Problem, but do you have your com.foo classes exported on
Plugin.xml->Runtime->Library Exporting?

Does anyone know how to select Export the entire Library? At my eclipse
this option is not selectable...

If you declare a plug-in class declared in plugin.xml then verify that
this class exists and is public. Also, adding -consolelog to your launch
config's arguments might give more clues.

Exporting my classes using "Plugin.xml->Runtime->Library Exporting" did the
trick. Thanks Karsten.
