JGit is a pure Java library implementing the Git version control system. It is an Eclipse project and started out as the Git library for EGit, which provides a Git integration into the Eclipse IDE.
Git git = Git.open(localPath); // add remote repo: RemoteAddCommand remoteAddCommand = git.remoteAdd(); remoteAddCommand.setName("origin"); remoteAddCommand.setUri(new URIish(httpUrl)); // you can add more settings here if needed remoteAddCommand.call(); // push to remote: PushCommand pushCommand = git.push(); pushCommand.setCredentialsProvider(new UsernamePasswordCredentialsProvider("username", "password")); // you can add more settings here if needed pushCommand.call();
针对github可优化未token方式，从github tokens这里新建一个自己的token，然后上面的Credential Provider可以直接使用
new UsernamePasswordCredentialsProvider("token", ""即可。
GitHub uses password authentication for https URLs and public-key authentication for SSH URLs
ssh-keygen -p -f file -m pem -P passphrase -N passphrase进行重置（如果创建时passphrase没有设置，使用”“代替即可）
JGit Authentication Explained这里提到了各个不同协议使用的区别。使用SSH的方式暂未验证。
Primary differences between SSH and HTTPS. This post is specifically about accessing Git repositories on GitHub.
Protocols to choose from when cloning:
plain Git, aka
Does not add security beyond what Git itself provides. The server is not verified.
If you clone a repository over git://, you should check if the latest commit’s hash is correct.
You cannot push over it. (But see “Mixing protocols” below.)
HTTPS will always verify the server automatically, using certificate authorities.
(On the other hand, in the past years several certificate authorities have been broken into, and many people consider them not secure enough. Also, some important HTTPS security enhancements are only available in web browsers, but not in Git.)
Uses password authentication for pushing, and still allows anonymous pull.
Downside: You have to enter your GitHub password every time you push. Git can remember passwords for a few minutes, but you need to be careful when storing the password permanently – since it can be used to change anything in your GitHub account.
If you have two-factor authentication enabled, you will have to use a personal access token instead of your regular password.
HTTPS works practically everywhere, even in places which block SSH and plain-Git protocols. In some cases, it can even be a little faster than SSH, especially over high-latency connections.
Doesn’t work with GitHub anymore, but is offered by some other Git hosts.
Works practically everywhere, like HTTPS.
But does not provide any security – the connection is plain-text.
Uses public-key authentication. You have to generate a keypair (or “public key”), then add it to your GitHub account.
Using keys is more secure than passwords, since you can add many to the same account (for example, a key for every computer you use GitHub from). The private keys on your computer can be protected with passphrases.
On the other hand, since you do not use the password, GitHub does not require two-factor auth codes either – so whoever obtains your private key can push to your repositories without needing the code generator device.
However, the keys only allow pushing/pulling, but not editing account details. If you lose the private key (or if it gets stolen), you can just remove it from your GitHub account.
A minor downside is that authentication is needed for all connections, so you always need a GitHub account – even to pull or clone.
You also need to carefully verify the server’s fingerprint when connecting for the first time. Many people skip that and just type “yes”, which is insecure.
(Note: This description is about GitHub. On personal servers, SSH can use passwords, anonymous access, or various other mechanisms.)
You can clone everything over
git://, but tell Git to push over HTTPS.
[url "https://github.com/"] pushInsteadOf = git://github.com/
Likewise, if you want to clone over
git:// or HTTPS, but push over SSH:
[url "email@example.com:"] pushInsteadOf = git://github.com/ pushInsteadOf = https://github.com/
These go to your git config file – sometimes
~/.gitconfig, or just run
git config --edit --global.
You can also set different pull and push URLs for every remote separately, by changing
remote.name.pushUrl in the repository’s own
