`clone`

public static void gitClone(String remoteUrl, File repoDir) {    try {        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) {                repo.close();            }        }    }}

`pull`

pull要在/.git目录中进行

public static void gitPull(File repoDir) {    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);            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) {                repo.close();            }        }    }}

`show status`

show status要在/.git目录中进行

public static void gitShowStatus(File repoDir) {    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);            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 {            if (repo != null) {                repo.close();            }        }    }}
