【问题描述】：
我只是尝试使用 maven、flyway 和 Google Cloud SQL 设置一个简单的 Hello World 概念验证。有关我正在使用的完整代码，请参阅 https://github.com/creyes17/mvn-flyway-cloudsql-test。 （问题发布在提交3b7bfa8e）。
每当我运行mvn flyway:migrate 时，无论我从哪个机器运行它，我都会收到以下错误：
[ERROR] Failed to execute goal org.flywaydb:flyway-maven-plugin:4.0.2:migrate (default-cli) on project mvn-flyway-cloudsql-test: com.google.apphosting.api.ApiProxy$CallNotFoundException: Can't make API call rdbms.OpenConnection in a thread that is neither the original request thread nor a thread created by ThreadManager -> [Help 1]
这是我的 pom.xml：

我已确认我可以使用 gcloud 工具使用相同的凭据直接登录到云 sql：gcloud sql connect REDACTED --user=$user。当我在打开的 mysql 工具中输入\s 时，我可以确认用户是相同的，并且连接与我一直使用的$instance 相同。我在尝试mvn flyway:migrate 之前和之后都尝试过使用gcloud 工具，但它不会改变错误消息。
我查看了Migrating to Google Cloud SQL using flyway, what jar files should be copied?，但我的错误信息不同。我还是尝试了修复（放入 mysql jdbc jar），但它根本没有改变错误消息。
感谢您的帮助！
