WARNING: unable to change permissions for everybody:

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:

Jun 04, 2015 12:12:11 AM com.google.api.client.util.store.FileDataStoreFactory setPermissionsToOwnerOnly
WARNING: unable to change permissions for everybody:
C:\Users\Quibbles\credentials\drive-api-quickstart

What am I doing wrong?

Edit: This is the complete error message.

Jun 04, 2015 5:11:39 PM com.google.api.client.util.store.FileDataStoreFactory setPermissionsToOwnerOnly
WARNING: unable to change permissions for owner: C:\Users\Quibbles\.credentials\drive-api-quickstart

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");

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");

This resolved my issue.

The actual problem is a bug in Google's API code for setPermissionsToOwnerOnly

The code was written to only work on Linux/Unix based systems and not Windows ACL based systems.

You can ignore the warning or write your own DataStore class that sets the permissions correctly for Windows.

I'm going to try to file a bug with Google on it too.
