java.lang.ClassNotFoundException: can't successfully load the class source

I am working on an Android project - so far so good. Today I added some extra Java code to the project - I will call it here calcCode. This is some code doing calculations in the background and is not Android specific - I will just be using it in my project.

I added that new code to a different package than my Android code under the same project.

So what I have is:

Project
 AndroidPackage
  AndroidCode
 SomeJaveCodePackage
  UtilityCode

For some reason, when I try to debug the calcCode I get this annoying source not found error. Still - the code runs and delivers the correct results as always. I took the calcCode from some other project and copied the files into my new Android project. When I couldn't see the source I deleted all the calcCode files and manually created them by first creating a class file under the relevant package and then copy-pasted the code in. I thought this will help Eclipse recognize the path of the classes.

I also tried to: "Edit Source Lookup Path" and add the source code of the class I was trying to debug.

This didn't change anything - I can still not debug the code. I read several answers to this issue on StackOverflow. Most deal with Junit and Tomcat and I followed their recommendations but it didn't change the situation.

Anyone knows why this is happening?

I have Eclipse Indigo.

EDITED after m0skit0's remarks: Thank you m0skit0 for the help. I meant to ask only one question (I might have mixed up stuff on the way). My question is: Why can't Eclipse find my own code while I debug it. It used to work in a former project (that I was able to follow the code through all the app's course during debug).

What I do is set a break point at

Tour myTour = new Tour("res/raw/td.csv", "readCSV");

Tour is my own hand-made class. When I press F5 in order to step into it I get the error: java.lang.ClassNotFoundException and in the code window I get Source not found and a button Edit source lookup path.

This is the call stack:

Thread [main] (Suspended)
    ClassNotFoundException(Throwable).<init>(String, Throwable) line: 286   
    ClassNotFoundException(Exception).<init>(String, Throwable) line: not available

The problem is solved. The sad thing is that I don't know the solution. What I did was simply to open a new project and use the code there. After I did this i could debug the code with no problem.

Sorry I couldn't contribute to REALLY solving this issue and help the community with the answer to my own question.

Thanks to all that tried to help, D.
