eclipse에서 git pull 할때 auth failed 에러

eclipse에서 git pull 할때 auth failed 에러가 발생한 경우 아래와 같은 방법으로 해결

1. In your Eclipse go to Window > Preferences > Network Connections > SSH2 (or just type "SSH2" in preferences window filter box).
2. In "Key Management" tab press "Generate RSA Key..." button. Optionally you can add comment (usually e-mail address) and passphrase to your key. Passphrase will be used during authentication on GitHub.
3. Copy your generated public key (in a box just below "Generate RSA Key..." button) and add it to your GitHub account.
4. Press "Save Private Key..." button to save your private RSA key into file. By default keys are stored in SSH2 home directory (see "General" tab).
