Should libraries (jar) go into the repository?

Question

When you start to use a third party library in Java, you add their jars to your project. Do you also add the jars to the repository or do you just keep a local installation. And if the latter, how do you sync between team members to be able to work?

Thanks.

Answer 1

Yes. You should add to the repository whatever is required for a developer on a clean system (aside from having the JDK and ant installed) to check out and build the project.
