    There are several alternatives:

    • If project A depends on project B, and both projects are in the same Eclipse workspace, you can just project B to project A’s build path (project properties / build path / project). This has the nice advantage that it will (optionally) automatically pull in project B’s JARs, plus updates to B will be used automatically by A, and you can debug into B’s code (even using hot code replace).
    • If A and B are fairly separate, just make B into a JAR (or several ones), then add these to A’s build path.
