在 https://developers.google.com/drive/上运行Java快速入门示例时web / quickstart / java？hl = hu 在NetBeans中，我收到了错误代码：

When running the Java quickstart sample at https://developers.google.com/drive/web/quickstart/java?hl=hu in NetBeans, I'm receiving the error code:

我做错了什么？

推荐答案

如果在实现无法更改所有者权限：C：\ Users \Quibbles.credentials\drive-api-quickstart
$ b之前发生同样的问题并浪费了数小时$ b只是一个警告。

Had the same issue and wasted hours before realizing that "unable to change permissions for owner: C:\Users\Quibbles.credentials\drive-api-quickstart"
is just a warning.

The real issue is the null pointer here.

InputStream in =
            DriveQuickstart.class.getResourceAsStream("/client_secret.json");

这一行对我来说是个问题。 in为空，因此为空指针。

This line was the issue in my case. "in" was null and hence the null pointer.

InputStream in    = new FileInputStream("<Full Path>\\client_secret.json");  

这解决了我的问题。
