我按照谷歌的帮助步骤，但凭据不起作用

Question

我正在尝试创建一个发送电子邮件并使用Google提供的Java教程的小程序，我在教程中创建了凭据，但是当我刮擦程序时弹出错误：

com.google.api.client.util.store.FileDataStoreFactory setPermissionsToOwnerOnly
ADVERTÊNCIA: unable to change permissions for everybody: C:\Users\HP\.credentials\gmail-java-quickstart

ADVERTÊNCIA: unable to change permissions for owner: C:\Users\HP\.credentials\gmail-java-quickstart
:run
Credentials saved to C:\Users\HP\.credentials\gmail-java-quickstart
Exception in thread "main" com.google.api.client.googleapis.json.GoogleJsonResponseException: 403 Forbidden
{
  "code" : 403,
  "errors" : [ {
    "domain" : "global",
    "message" : "Insufficient Permission",
    "reason" : "insufficientPermissions"
  } ],
  "message" : "Insufficient Permission"
}

有人可以帮助我吗？
