is there a way to run only my class

I have a large application with multiple projects and dependencies. To debug a functionality, i want to write a new java class in the project source folder with a main method, so i get all required jars, and run it.

Is there a way to run only my class,,, instead of scanning everything in the workspace and failing saying some class in some project has a missing dependency.

If my class does not require that project, why should I care about it?

Idea may scan it however should run my class.

Any suggestion on how to do this????
