        Git git = Git.cloneRepository()
                .setURI(remoteUrl)
                .setDirectory(repoDir)
                .call();

        logger.info("Cloning from " + remoteUrl + " to " + git.getRepository());
    } catch (Exception e) {
        logger.info(e.getMessage());
    }
}

`checkout`

checkout要在/.git目录中进行

public static void gitCheckout(File repoDir, String version) {
    File RepoGitDir = new File(repoDir.getAbsolutePath() + "/.git");
    if (!RepoGitDir.exists()) {
        logger.info("Error! Not Exists : " + RepoGitDir.getAbsolutePath());
    } else {
        Repository repo = null;
        try {
            repo = new FileRepository(RepoGitDir.getAbsolutePath());
            Git git = new Git(repo);
            CheckoutCommand checkout = git.checkout();
            checkout.setName(version);
            checkout.call();
            logger.info("Checkout to " + version);

            PullCommand pullCmd = git.pull();
            pullCmd.call();

            logger.info("Pulled from remote repository to local repository at " + repo.getDirectory());
        } catch (Exception e) {
            logger.info(e.getMessage() + " : " + RepoGitDir.getAbsolutePath());
        } finally {
            if (repo != null) {

            }
        }
    }
}

`pull`

        logger.info("Error! Not Exists : " + RepoGitDir.getAbsolutePath());
    } else {
        Repository repo = null;
        try {
            repo = new FileRepository(RepoGitDir.getAbsolutePath());
            Git git = new Git(repo);
            PullCommand pullCmd = git.pull();
            pullCmd.call();

            logger.info("Pulled from remote repository to local repository at " + repo.getDirectory());
        } catch (Exception e) {
            logger.info(e.getMessage() + " : " + RepoGitDir.getAbsolutePath());
        } finally {
            if (repo != null) {

            }
        }
    }
}

`show status`

public static void gitShowStatus(File repoDir) {

    if (!RepoGitDir.exists()) {
        logger.info("Error! Not Exists : " + RepoGitDir.getAbsolutePath());
    } else {
        Repository repo = null;
        try {
            repo = new FileRepository(RepoGitDir.getAbsolutePath());
            Git    git    = new Git(repo);
            Status status = git.status().call();
            logger.info("Git Change: " + status.getChanged());
            logger.info("Git Modified: " + status.getModified());
            logger.info("Git UncommittedChanges: " + status.getUncommittedChanges());
            logger.info("Git Untracked: " + status.getUntracked());
        } catch (Exception e) {
            logger.info(e.getMessage() + " : " + repoDir.getAbsolutePath());
        } finally {
