Java库依赖项

Question

What is the easiest way to see the libraries dependencies in Java project (eclipse)?
I am using Spring MVC and Hibernate so right now there are a lot of jar files and I even do not remember which one of them are responsible for what.

Answer 1

See them how?

If you're using maven, use the dependency plugin's dependency:tree to get a hierarchical representation of what depends on what.

If you're not, ew; manual management of transitive dependencies sucks! You can use something like Dependency Finder or JDepend to provide similar info.

Answer 2

Not sure if this is what you mean, but to start with you can right-click the project (in Eclipse) and look at Properties -> Java Build Path . The Libraries tab should list what libraries you're using on your build path. (But you probably knew that.)

If it's a simple standalone project, you could of course always remove a library and see what interesting new errors pop up ;-)

For more complicated projects with interdependencies, it can take quite a bit of fiddling to get all your dependencies right. I generally recommend setting up a "core" project which holds (and exports) most of your third-party JARs (better yet, use user libraries , and putting that project on the build path of your other projects.

Edit after reading your comment: Ah, gotcha... you might be interested in the Plug-in Dependency Visualisation incubator project then - haven't used it myself but it sounds like it could do what you're after. Hope that helps!
