Google app engine 获取403错误，但正在部署版本，流量为0%

我正在使用maven插件1.9.60和JDK 8

运行命令

mvn安装appengine:update-Dappengine.additionalParams=“--service\u account\u json\u key\u file=client secret.json”

我可以看到部署的版本，但流量为0%。日志显示错误如下。有人能建议如何解决这个问题吗

您遇到的问题是由于服务帐户上缺少角色造成的。它可能分配了“应用引擎部署器”角色，但缺少“数据存储索引管理员”角色，这导致在发布到appengine.google.com/api/Datastore/Index时出现403s/

添加该角色后，您需要重新生成私钥（您将其命名为client-secret.json），因为旧的私钥没有新的权限

有关部署GAE应用程序所需角色的更多信息，请参见第节

注：感谢您提供完整的复制。它总是很有用。
现在，由于您的代码中既没有index.yaml，也没有datastore-indexes.yaml，我无法解释与数据存储相关的角色的需要。我将尝试对此进行更深入的研究。我没有编写任何访问数据存储API的代码。我将尝试按照您的建议添加数据存储索引管理员角色。我添加了数据存储索引管理员角色，重新生成了密钥文件，它成功了。谢谢你的帮助。
