无法删除由 JGIT 创建的存储库文件夹

问题描述 投票：0回答：2

我无法删除包含使用 

jgit
创建的克隆存储库的文件夹。我尝试了各种实用程序删除方法，但都不起作用。使用
FileUtils.deleteDirectory(file)
时抛出的错误如下

java.nio.file.AccessDeniedException: \repositories\Test\Test\.git\objects\pack\pack-21cdd19e90e9e6bd2e8d295ea04201969594fe96.idx

尝试了以下，

  1. 我看到了一系列其他答案，例如 [1] 和 [2]。他们都关心这样的情况：他们先用
    jgit
    创建了一个存储库，然后立即将其删除。在我当前的场景中，我想检查一个存储库是否已经在给定路径上被克隆，如果存在则删除。完成此任务后，我想在同一路径上使用 
    jgit
    克隆一个存储库。
  2. 我尝试过使用 
    jgit
    创建存储库的情况，关闭我的服务器。再次启动它，然后简单地调用一个函数来删除之前创建的文件夹。这再次失败并出现相同的错误。
  3. 我还从我的初始代码和 pom 中完全删除了 jgit，因为它可能会被加载到类路径中。尝试删除时我仍然遇到相同的错误。重新启动后再次尝试检查，问题仍然存在。
  4. 然而，当我从另一个 Java 程序运行相同的删除代码时，它成功了。

[1] 如何通过JGit java库克隆的Java代码删除本地存储库？
[2] 如何在通过 JGit 克隆 repo 后释放文件系统锁

这里是原始代码片段供参考，

    File file = null;
    try {
        file = new File(localRepositoryPath);

        // Delete directory if already present
        String localRepositoryParentPath = GitUtils.getRepositoryPath(projectName, null);
        File parentDirectory = new File(localRepositoryParentPath);
        FileUtils.deleteDirectory(parentDirectory);

        // Create directory where repository will be cloned
        if(!file.mkdirs()) {
            throw new GitServiceException(
                GitUtils.getCloneFailureMessage("Unable to create directory",
                    projectName,
                    repoName));
        }
    } catch (NullPointerException | SecurityException | IOException e) {
        logger.info(Arrays.toString(e.getStackTrace()));
        logger.error("IO Error cloning repository {} and project {}. Stacktrace {} ",
            repoName,
            projectName,
            e.getStackTrace());
        throw new GitServiceException(
            GitUtils.getCloneFailureMessage("IO Error while cloning",
                projectName,
                repoName));
    }

    // Clone the git repository
    try (Git git = Git.cloneRepository()
            .setURI(repoUrl)
            .setDirectory(file)
            .setBranchesToClone(List.of("refs/heads/" + branchToClone))
            .setBranch("refs/heads/" + branchToClone)
            .setCredentialsProvider(new UsernamePasswordCredentialsProvider( "token", this.credentials.getGitToken()))
            .call();
    ) {
        logger.info("Successfully cloned branch {} on path {} for repository {} and project {}",
            branchToClone,
            localRepositoryPath,
            repoName,
            projectName);
    } catch (Exception exception) {
        logger.error("Error cloning repository {} and project {}. Stacktrace {} ",
            repoName,
            projectName,
            exception.getStackTrace());
        throw new GitServiceException(
            GitUtils.getCloneFailureMessage("Unable to clone repository locally",
                projectName,
                repoName));
    }

显然是 Apache Commons IO 函数抛出了错误。递归遍历所有文件并使用 

java.io
delete 命令删除它们非常好。

这里是用于参考的代码片段，

public static boolean deleteDirectory(File file) {
    File[] children = file.listFiles();
    if (children != null) {
        for (File child : children) {
            deleteDirectory(child);
        }
    }
    return file.delete();
}

在 Git 克隆后使用 .close() 方法，这将解决您的问题。

try (Git git = Git.cloneRepository()
        .setURI(repoUrl)
        .setDirectory(file)
        .setBranchesToClone(List.of("refs/heads/" + branchToClone))
        .setBranch("refs/heads/" + branchToClone)
        .setCredentialsProvider(new UsernamePasswordCredentialsProvider( "token", this.credentials.getGitToken()))
        .call()
        .close();
