Java JGit克隆从gerrit失败，没有用户名或密码

我对JGit版本3.0.0.201306101825-r有问题。以下是我的克隆功能：

public static void cloneRepository(String localRepositoryPath, String remoteRepositoryURI, String branch, String username, String password) throws IOException, InvalidRemoteException, GitAPIException {
    File workDir = createFolder(localRepositoryPath);
    CloneCommand clone = Git.cloneRepository();
    clone.setBare(false);
    clone.setCloneAllBranches(false);
    clone.setBranch(branch);
    clone.setDirectory(workDir).setURI(remoteRepositoryURI);
    if (StringUtils.isNotEmpty(username)) {
        UsernamePasswordCredentialsProvider credentials = new UsernamePasswordCredentialsProvider(username, password);
        clone.setCredentialsProvider(credentials);
    }
    Git git = clone.call();
}

我正试图从gerrit克隆一个存储库，每个人都有权阅读它。”git克隆ssh://gerrit.xx.com:29418/project/test'从终端正常工作，但使用Jgit我无法克隆存储库。这是我得到的一个错误：

如何解决这个问题的想法非常受欢迎

我认为git克隆ssh://gerrit.xx.com:29418/project/test 之所以有效，是因为它使用客户端maschine上的登录用户名，并对gerrit执行基于密钥的身份验证

通常，您不能使用ssh执行任何匿名通信。JGit可能不知道它的环境，您必须显式地提供用户名和适当的ssh密钥，特别是在启用ssh的用户上下文之外运行Java代码时。使用UsernamePasswordCredentialsProvider将无法使用ssh访问gerrit

---

我建议您使用HTTP对gerrit进行匿名读取访问。git克隆http://gerrit.xx.com:[port]/test应完成此工作。当[port]是gerrit安装侦听HTTP请求的端口时。我认为默认的ist 8080。

如果您没有使用像Eclipse这样具有适当支持的程序，您可以尝试将GIT_SSH设置为外部可执行文件来运行您的进程，这样可以代表您进行身份验证
