Google Cloud App Engine和Spring Boot gradle部署问题

Question

我有问题。 我想将Spring Boot Gradle应用程序部署到GC App Engine。 我使用命令：

渐变appengineDeploy

它实际上有效，但是当我尝试在浏览器中打开应用程序时，它显示：

Error: Server Error
The server encountered an error and could not complete your request.
Please try again in 30 seconds.

因此该应用已成功部署，但启动时遇到问题。

所以是由

引起的

Unable to set ApplicationName - SQLAdmin client already initialized.

我的build.gradle看起来像这样
