I decided to try BitBucket and Git but I\'m confused on how to configuring eGIT ( Eclipse GIT plugin ) to connect to Bitbucket\'s GIT repo.
Anybody know any document
Your question is essentially asking for documentation on using egit - you can find that all here:
In particular, the user manual that is linked from there describes both how to clone a repository using EGit and work with an existing repository — it's not clear from your question which situation you are in. The only difference between using a BitBucket git repository and one from another repository-hosting service is the URL, essentially. Broadly speaking, you should use the SSH URL if possible.
