我只是想使用maven，flyway和Google Cloud SQL进行简单的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，无论从哪台机器运行它，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：

我已经确认我能够使用相同的凭据使用 gcloud 工具直接登录到云 sql：gcloud sql connect REDACTED --user=$user.当我在打开的mysql工具中键入s时，我可以确认用户是相同的，并且连接与我一直使用的$instance相同。我在尝试之前和之后尝试使用gcloud工具mvn flyway:migrate但它不会更改错误消息。
我查看了使用flyway迁移到Google Cloud SQL，应该复制哪些jar文件？，但我的错误消息不同。无论如何，我都尝试了修复程序(放入mysql jdbc jar中)，但它根本没有更改错误消息。
感谢您的任何帮助！
我在谷歌与Jinjun进行了交谈，他能够指出我一些不同的Google文档。我需要使用他们的MySQL SocketFactory并重新格式化jdbc url字符串。
具体来说，我在pom.xml中添加了以下依赖项：
<!-- https://mvnrepository.com/artifact/com.google.cloud.sql/mysql-socket-factory-connector-j-6 -->
<dependency>
<groupId>com.google.cloud.sql</groupId>
<artifactId>mysql-socket-factory-connector-j-6</artifactId>
<version>1.0.2</version>
</dependency>
然后，我将 JDBC URL 连接器字符串更改为
jdbc:mysql://google/hello_world?cloudSqlInstance=${instance}&socketFactory=com.google.cloud.sql.mysql.SocketFactory
我已经更新了我的示例 github 存储库，并在几台不同的机器上对其进行了测试以测试可移植性。
