在NetBeans中运行https://developers.google.com/drive/web/quickstart/java?hl=hu上的Java快速入门示例时,我收到错误代码:
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
我究竟做错了什么？
编辑:这是完整的错误消息.
