jgit拉取git代码到本地，获取所有分支

引入jgit

<dependency>
    <groupId>org.eclipse.jgit</groupId>
    <artifactId>org.eclipse.jgit</artifactId>
    <version>3.7.0.201502260915-r</version>
</dependency>

初始化一些变量

1.拉远程分支到本地：

   /**
     * 拉取远程分支到本地
     *
     * @return
     */
    public static String cloneRepository() {
        String msg = "";
        try {
            Git git = Git.cloneRepository()
                    .setURI(REMOTEREPOURI)
                    .setCredentialsProvider(new UsernamePasswordCredentialsProvider(USER, PASSWORD))
                    .setBranch("master")
                    .setDirectory(new File(LOCALPATH)).call();
            msg = "git init success！";
            ListBranchCommand listBranchCommand = git.branchList();
            System.out.println(listBranchCommand.getRepository().getBranch());
        } catch (Exception e) {
            System.out.println(e.getMessage());
            msg = "git已经初始化！";
        }
        System.out.println(msg);
        return msg;
    }

运行结果：

可以看到项目目录下生成了demo文件夹，代码已经拉了下来

 

 2.获取所有分支

 /**
     * 获取所有分支
     *
     * @param url
     */
    public static void getRemoteBranchs(String url) {
        try {
            Collection<org.eclipse.jgit.lib.Ref> refList;

            UsernamePasswordCredentialsProvider pro = new UsernamePasswordCredentialsProvider(USER, PASSWORD);
            refList = Git.lsRemoteRepository().setRemote(url).setCredentialsProvider(pro).call();
            List<String> branchnameList = new ArrayList<>(4);
            for (Ref ref : refList) {
                String refName = ref.getName();
                if (refName.startsWith("refs/heads/")) {                       //需要进行筛选
                    String branchName = refName.replace("refs/heads/", "");
                    branchnameList.add(branchName);
                }
            }

            System.out.println("共用分支" + branchnameList.size() + "个");
            branchnameList.forEach(System.out::println);
        } catch (Exception e) {
            System.out.println("error");
        }
    }

运行结果：
