Question

I think most of you will know, programmers often reuse code from other software. I think, most of the time it is a good idea. But if you use code from another project your program depends on the other project.

I my current case I got three java projects A, B and C. Now A uses B and B uses C. I’m using eclipse IDE and added B to the buildpath of A and C to the buildpath of B. Now there is an compiler error that A can’t resolve something from C. So I have to add C to the buildpath of B.

So what is the best way, to resolve the dependencies while keeping your programm as independent as possible from other projects?

I would like to know is in general and in reference to my current situation. Are there better ways to do this? I.e. there are classpath settings in the launch / debug configuration view, but I think they won’t help at compile time.

Thanks in advance.

This sounds like part of the problem set fixed by Maven. Using Maven and Eclipse, namely m2eclipse, you can have projects use other projects and all the dependency resolution is handled for you.
