Java 使用 JGit 执行 Git 命令

某些时候需要使用Java代码执行Git操作，可以使用JGit来实现。

<dependency>
    <groupId>org.eclipse.jgit</groupId>
    <artifactId>org.eclipse.jgit</artifactId>
    <version>4.9.3.201807311005-r</version>
</dependency>

clone project

public static void main(String[] args) throws GitAPIException {
          
   
    Git git = Git.cloneRepository().setURI("xxx.git")
            .setCredentialsProvider(provide())
            .call();
    git.checkout()
            .setCreateBranch(true)
            .setName("your-branch")
            .call();
    File file = git.getRepository().getDirectory();
    String projectPath = file.getParent();
}

private static UsernamePasswordCredentialsProvider provide() {
          
   
    return new UsernamePasswordCredentialsProvider(username, password);
}

push project

private void pushFiles(GitlabProject project, File file)
        throws GitAPIException, URISyntaxException {
          
   
    Git git = Git.init().setDirectory(file).call();
    RemoteAddCommand remoteAddCommand = git.remoteAdd();
    remoteAddCommand.setName("origin");
    remoteAddCommand.setUri(new URIish(project.getHttpUrl()));
    remoteAddCommand.call();
    git.add().addFilepattern(".").call();
    git.commit().setMessage("init").call();
    git.push().setCredentialsProvider(new UsernamePasswordCredentialsProvider(username, password)).call();
}
