Java Google app engine无法创建DevAppServer
当尝试创建本地应用服务器来测试我的web应用时，我完全无法这样做。其他人也看到了同样的错误，并被告知这是JDK>12的问题，但我只使用Java8。我可以正常部署应用程序，但不能创建本地服务器。我已经通过powershell使用本机gcloud CLI、intellij插件和maven插件进行了尝试，每次都遇到同样的问题。任何帮助都将不胜感激 stacktraceJava Google app engine无法创建DevAppServer,java,maven,google-app-engine,google-cloud-platform,gcloud,Java,Maven,Google App Engine,Google Cloud Platform,Gcloud,当尝试创建本地应用服务器来测试我的web应用时，我完全无法这样做。其他人也看到了同样的错误，并被告知这是JDK>12的问题，但我只使用Java8。我可以正常部署应用程序，但不能创建本地服务器。我已经通过powershell使用本机gcloud CLI、intellij插件和maven插件进行了尝试，每次都遇到同样的问题。任何帮助都将不胜感激 stacktrace Apr 18, 2020 9:27:22 PM com.google.cloud.tools.appengine.operations

我也遇到了同样的问题，在尝试了几个小时之后，我发现您可以作为一个独立的应用程序使用。这样做之后，我的应用程序现在可以在部署时在本地和远程运行 这就是我的工作 我删除了
main/webapp/WEB-INF/appengine WEB.xmlmain/appengine/app.yamlruntime:java11
war应用程序，然后指定了
application {
mainClassName = "my.package.Main"
}
不确定这是否必要，但我也更新了这个
java {
sourceCompatibility = JavaVersion.VERSION_11
}
与你的问题无关，但是
@SpringBootApplication
class MyApplication
object Main {
@JvmStatic
fun main(args: Array<String>) {
runApplication<MyApplication>(*args) {
setBannerMode(Banner.Mode.OFF)
}
}
}
