comparingReferences sample plugin Help !!!

Hello Siddique,

Check if you've added any of IDEA jars (like idea.jar) to the plugin module
classpath. This should not be the case since all necessary jars will be automatically
caught through IDEA sdk.
Please also cleanup the sandbox after you change the classpath back.

As the matter of fact this is a classloader issue since some IDEA classes
are loaded by wrong classloader

Hi Guys,

I am a newbie to IntelliJ and also the Plugin development. I couldn't
get this sample plugin to work/test.

This is what I did...

I opened up the IntelliJ Plugin project

1.C:\idea-5.0.1-dev\examples\comparingReferences\comparingReferences.i
pr

2. Assigned JDK5.0 came along with IntelliJ to its module

3. Created a default sandbox environment for its plugin module

4. Built the project

5. Ran the project by hitting the run button.

Here is my console
