我正在尝试使用maven archetype
使用此命令构建项目来创建hello-endpoint-framework。
mvn archetype:generate -Dappengine-version=1.9.63 -Djava8=true -DCloudSDK_Tooling=false -Dapplication-id=your-app-id -Dfilter=com.google.appengine.archetypes:
我设置-Djava8=true因为我想在java8中运行它。
这是pom.xml文件。

在此之后，我运行此命令mvn clean package构建项目。然后我运行mvn appengine:run但我得到了这个错误。appengine-maven-plugin：1.3.1 运行失败非零退出
我用-e重新运行我的命令，这就是我得到的。

我只了解一个错误项目没有定义所需的最低 Maven 版本。我在pom中设置了最低版本，但仍然有相同的错误。
在此之后，我还尝试更新gcloud组件gcloud components update但是无法解决此错误。
我正在使用JDK10
我还有一个问题，这个项目是针对java7还是Java8。 我想在java8中运行这个项目，这就是我设置-Djava8=true的原因但是我不认为这个项目是为java8环境创建的，是吗？如果不是，我该怎么做？
那么应用程序引擎-专家-插件错误呢？我该如何解决这个问题？为什么我看到这个，云SDK有任何问题吗？或者有任何其他原因。
如下所述：
<properties>
<maven.compiler.source>1.7</maven.compiler.source>
<maven.compiler.target>1.7</maven.compiler.target>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>
这是Java 7，所以，如果你想用Java 8运行它，你必须将1.7的两个外观都更改为1.8。
appengine-maven-plugin的错误在于您尝试使用 Java 7，同时在命令中使用 Java 8。
