知道是什么导致了这个错误以及如何解决它？

Answer 1

以防万一其他人有这个问题：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>

这将重新打包 jar 以便谷歌可以执行它

回答这个老问题：

在使用 appdeploy 命令时，即使我在 GAE 中也遇​​到了类似的错误。

我做了两件事来解决这个问题：

1 . 确保 app.yaml 文件指定了资源。 在某些情况下，VM 没有足够的内存来运行应用程序并关闭。

resources:
  cpu: 2
  memory_gb: 2.0

2 . 像上面@Roie 的回答一样，在 maven 执行中添加重新打包目标
