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.

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.
