ClassNotFoundException when developing Eclipse plug-in

Question

Hi!

I'm working on an Eclipse plug in (basically it gets posts from social networks such as Facebook and Twitter). I have various plug-in projects and I have one of them which makes use of another. I include the latter project in my build path and it compiles ok. However when I run the projects (Run As --> Eclipse Application) I get a java.lang.ClassNotFoundException.

Previously I had a similar issue but I was referencing a JAR file so apart from including it in the build path, I included it in the classpath from the Runtime tab in Eclipse and it worked fine. However Eclipse only seems to allow JAR files and not plug-in projects in the workspace to be included in the classpath...

I've tried various ways to try to include the plug-in project I need but the java.lang.ClassNotFoundException still comes up...

I'd really appreciate any help! 10x in advance. Krt_Malta

Answer 1

You need to add the plugin you are using as a dependency of the plugin you are writing. Once that is setup open the Run Configuration for your project, click on the Plug-Ins tab and select the "Add Required Plugins" button.
