In a bigger project we might be using tons of JARs. How do I find out which JARs are being used by a certain module/package in the project (not the whole project). Any tool, technique, etc?

  • If you were to use Maven for dependency management, you could have a nice dependency graph with the Eclipse plugin – Robert Jan 19 '11 at 11:13

Bigger projects typically use a build tool like maven or ant. maven has the maven dependency plugin to list the dependencies for a particular project which you invoke by mvn dependency:list. In case of ant, it depends on the way the build script is written.

Maybe you should give more details about your project environment and you may get better answers.
