如果有人有任何想法，请帮助我。我在过去的 12 个小时里一直在苦苦挣扎，并且无法弄清楚发生了什么，因为我对此很陌生。

【解决方案1】：

在您的 pom.xml 中将 <packaging>jar</packaging> 更改为 <packaging>war</packaging> 可能会为您解决问题。

【讨论】：

【解决方案2】：

这可能是复制+粘贴错误，但您的 yaml 文件的缩进不正确（这将使其无法解析）。最后一行应该有 1 级缩进：

runtime: java
env: flex
runtime_config:
    jdk: openjdk8

要查明问题，您还可以尝试分两步进行部署，执行mvn appengine:stage 以准备要部署的文件，然后使用目标/暂存目录中的gcloud app deploy 手动部署。
