如何在JGit中创建基于另一个本地分支的本地分支

File gitDir = new File("/path/to/your/local/repository");
Git git = Git.open(gitDir);

List<Ref> branches = git.branchList().call();
Ref sourceBranch = null;

for (Ref branch : branches) {
    if (branch.getName().equals("refs/heads/source_branch")) {
        sourceBranch = branch;
        break;
    }
}

Ref newBranch = git.checkout()
        .setName("new_branch")
        .setStartPoint(sourceBranch.getObjectId().getName())
        .call();

git.push()
        .add("new_branch")
        .call();
