我的春季启动应用程序在本地计算机上运行良好。但是当我尝试使用此命令在GAE上进行部署时，它会给我以下错误

知道导致此错误的原因以及解决方法吗？
答案 0 :(得分：0)
以防万一其他人遇到此问题： 将以下内容添加到pom.xml：
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.0.5.RELEASE</version>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
这将重新包装jar，以便Google可以执行

回答这个老问题：
使用appdeploy命令时，即使在GAE中也遇到类似的错误。

我做了两件事来解决这个问题：
1 。确保app.yaml文件已指定资源。在某些情况下，VM没有足够的内存来运行应用程序，因此它会关闭。
resources:
cpu: 2
memory_gb: 2.0
2 。就像上述@Roie的答案一样，在Maven执行中添加 repackage 目标
