Eclipse Inspect(Ctrl+shift+I) not working

This might be useful:

Find the thread in your debug window that you are in the breakpoint for. Right click on it. Under relaunch should be an edit launch configuration selection. Select that.

Select Source tab. Add. Java Project. Select the java project that the code exists in.

Also, in your launch configuration, be sure that the source path is correctly specified.

That is to say: Run/Debug Configurations / Source tab / Add... / Java Project

Make sure the project containing your source code is in that list!

I solved this problem by did the following:

Right click on the project ->build path -> select source tab -> add folder and then i added the folder which contains the java classes.
