Java Google drive API没有列出我的所有文件

Java Google drive API没有列出我的所有文件,java,google-drive-api,Java,Google Drive Api,我正在使用一个非常简单的示例在google drive上检索我的文件。有两件奇怪的事 我第一次运行示例时,google说“应用程序希望访问您的文件”。嗯,我确认了。但是,第二次,它说“应用程序想要离线访问”。。。啊。。。为什么? 可能吧(但我不确定),在我第二次确认之后,我只得到我通过这个应用程序上传的文件 代码是 package com.google.api.services.samples.drive.cmdline; import com.google.api.client.auth.o
