How to automatically change Eclipse build path when I check out Git branches

I'm using Eclipse Helios and EGit 0.11.3.

I have a project where different branches use different versions of some of the libraries on my Java build path. For example, branch_old uses foo_lib_v1.0.jar while branch_new uses foo_lib_v2.0.jar.

If I'm wor开发者_如何学Goking on branch_new and I need to checkout branch_old to test something, it's a bit of a hassle: I must manually reconfigure the build path in Eclipse before the project can build successfully.

Is there a way to store Eclipse's Java build path configuration for my project in git, so that when I check out a branch the build path is automatically modified? If not, is there another way to achieve the same result?

Thanks.

I see several choices here:

• store project files (.classpath and .project) in Git as part of your branch. This way you would have to store all your dependencies in Git too, which is a hassle if you have a lot of them.
• use Maven (m2eclipse plugin) and store project definition (pom.xml) file as part of your version control. Maven will greatly simplify your project dependency configuration

More information on m2eclipse plugin can be found at http://www.sonatype.com/books/m2eclipse-book/reference/

Should work: Put the .buildpath under version control. So its checkouted every time you switch the branches.

AFAIK Eclipse stores his build classpath in a file like .classpath(?) You can just add the file to git and have an own config for each branch.

Define several user libraries in your workspace, such as FooLib1, FooLib2, FooLib2. Then in the project's build path at a given branch reference the appropriate version of the library. Make sure you include project metadata files such as .classpath in your git repository and you should be set.
