How to use bitBucket with EGit in Eclipse

Git is becoming more and more popular these days, and when we really use version control systems like Git or SVN, we actually want to share our codes with other developers. Thus, we do need a Git server to host the codes, like www.bitBucket.org, which is a Git server offering free limited use.

To set up a project in Eclipse, and push the project to bitBucket, you need to do the following steps:
(1) install EGit in Eclipse (http://www.eclipse.org/egit/);
(2) create an Eclipse project, e.g. HelloWorld; right click the project, and select Team->Share project... to add the project under Git control; right click the project again, and select Team->Add to index to add all the files of the project under version control; right click the project again, and select Team->Commit... to commit all the files;
(3) open an account on www.bitBucket.org, e.g. your account name is myaccount;
(4) configure the SSH in Eclipse:
click your project HelloWorld;
open menu Window->Preference->General->Network Connections->SSH2;
since now you have no SSH keys (bitBucket needs SSH keys for SSH authorization), select Key Management tab and click the button Generate RSA Key... (You can also use DSA keys);
then you can see the public key in the text area, and you need to copy the public key and save it in your account on bitBucket (Account->SSH keys); you also need to click the button Save Private Key... to save the private key to your local directory;
click the General tab, and click the Add Private Key... button to choose the private key that you just saved;
click the OK button to apply all the changes;
(5) on bitBucket, create a repository named HelloWorld, and then you can get the SSH address of the repository as:
ssh://git@bitbucket.org/myaccount/HelloWorld.git
(6)right click the project in Eclipse, and select Team->Remote->Push...;
then enter the SSH address and choose SSH as the protocol; Click the Next> button;
(7) click Add all branches spec button only, and then click the Next> button;
(8) click OK; 

Till now, other developers can clone the project resided on bitBucket, and they can also push changes to the repository.
However, although you can push changes to the remote repository, you cannot pull changes from the repository, since the pull operation is not configured to work with the remote repository.
To solve this problem, you have to add the following lines to the Git configuration file (in your eclipse project folder .git/config):
[remote "origin"]
url = ssh://git@bitbucket.org/myaccount/HelloWorld.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
