【问题描述】：
我的 Spring Boot 应用程序在本地机器上运行良好。但是当我尝试使用这个命令在 GAE 上部署时，它给了我以下错误
mvn appengine:deploy

知道是什么导致了这个错误以及如何解决它吗？
【问题讨论】：
-
你能分享你的 pom 和完整的构建输出吗？看起来您正在部署标准 jar，而不是 Spring Boot 重新打包的 jar
-
@AndyWilkinson pom.xml 代码添加有问题。
-
你已经注释掉了 Spring Boot 的 Maven 插件。你用什么来生成一个可执行的 jar？
-
@AndyWilkinson 我认为 appengine-maven-plugin 会完成这项工作。如果我错了，请纠正我。
-
不根据文档：cloud.google.com/appengine/docs/flexible/java/dev-java-only。 Spring Boot 的 Maven 插件是组装插件的更易于使用的替代品
