java - JGit 错误-> 由 : java. 引起 lang.NoSuchMethodError: No virtual method toPath()

Question

我正在尝试在 Android Java 上克隆存储库，但在调用方法 toPath() 时出现错误。显然 File 对象没有 toPath() 方法。

public void gitClone() throws GitAPIException {

    // File dir = new File(_ctx.getExternalFilesDir(null) + File.separator + "openshift_files");
    Bundle b2 = getIntent().getExtras();
    //File localPath = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS).getAbsolutePath());
    final File localPath = new File(getExternalFilesDir(null) + File.separator + getCurrentApp().getName());

    Git.cloneRepository()
            .setURI(getUrlGit())
            .setDirectory(localPath)
            .setCredentialsProvider(new UsernamePasswordCredentialsProvider(b2.getString("OPEN_SHIFT_USER"), b2.getString("OPEN_SHIFT_PASSWORD")))
            .call();
    System.out.println("Success!");
}

这是堆栈跟踪

您使用的 JGit 版本太新了。从 JGit 4.0.0 开始，最低 Java 版本从 Java 5 提高到 Java 7 ( see Eclipse documentation here )。 JGit 使用 Java 7 Path API，它不适用于您正在使用的 JDK。

您应该降级到 JGit 3.7.1(这是 3.x 系列的最新版本)。
