Question

我正在开发一个涉及将git存储库克隆到本地目录的项目。

我通读the tutorial，我的代码如下：

/*
 * Clones a github project to the designated directory and checks it out. (Both prefix and postfix)
 * <p>
 * @param buildPath - String, the path where the directories will be created and the projects built.
 * @param bugID - String, the bug's id.
 * @param projectURL - String, the github URL used to clone the project.
 */
public void DownloadAndSetup(String buildPath, String bugID, String projectURL, String prefixHash, String postfixHash) throws InvalidRemoteException, TransportException, GitAPIException {
    String generalPath = buildPath+File.separator+bugID;
    String prefixPath = generalPath+File.separator+"prefix";
    String postfixPath = generalPath+File.separator+"postfix";
    // Cloning & checking out to prefix
    Git gitPrefix = Git.cloneRepository().setURI(projectURL).setDirectory(new File(prefixPath)).call();
    gitPrefix.checkout().setCreateBranch(true).setName("new-branch").setStartPoint(prefixHash).call();
    // Cloning & checking out to postfix
    Git gitPostfix = Git.cloneRepository().setURI(projectURL).setDirectory(new File(postfixPath)).call();
    gitPostfix.checkout().setCreateBranch(true).setName("new-branch").setStartPoint(postfixHash).call();
}

但是当我跑步时：

public static void main(String[] args) throws InvalidRemoteException, TransportException, GitAPIException {
    GitDownloader gd = new GitDownloader();
    String buildPath = "C:\\Users\\dario_000\\Dropbox\\SheffInternship\\wsp\\AutoEv\\src\\tests";
    gd.DownloadAndSetup(buildPath, "download", "https://github.com/jhy/jsoup.git", "1e9ae842ca94f326215358917c620ac407323c81", "04e256ce9571e4239403b657126ce8eb30ad6776");
}

我收到以下错误：

    ... 6 more

有人有任何建议吗？

JGit依赖于JSch和JavaEWAH，显然JSch不在你的运行时类路径上。

您必须手动将所需的库添加到类路径中，或者让类路径由例如Maven或OSGi（工具）。

使用JGit将存储库克隆到本地目录
