appengine-maven-plugin：1.3.1运行失败非零退出

我正在尝试使用maven archetype创建hello-endpoint-framework
我用这个命令来构建项目。

 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。

   4.0.0 war 1.0-SNAPSHOT org.azeem.endpoints endpoints  1.7 1.7 UTF-8     <!-- com.google.appengine appengine-endpoints 1.9.53 -->    com.google.endpoints endpoints-framework 2.0.7    com.google.appengine appengine-api-1.0-sdk 1.9.53   javax.servlet servlet-api 2.5 provided   javax.inject javax.inject 1     ${project.build.directory}/${project.build.finalName}/WEB-INF/classes   com.google.cloud.tools appengine-maven-plugin 1.3.1      com.google.cloud.tools endpoints-framework-maven-plugin 1.0.0   YOUR-PROJECT-ID.appspot.com    org.codehaus.mojo versions-maven-plugin 2.1   compile  display-dependency-updates display-plugin-updates        

在此之后我运行此命令mvn clean package来构建项目。 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重新运行命令这就是我得到的。

我理解只有一个错误Project没有定义Maven所需的最低版本。 我在pom中设置了最小版本，但仍然是同样的错误。

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

我还有另一个问题，这个项目是针对java7还是针对java8 。 我想在java8中运行这个项目，这就是为什么我设置-Djava8=true但我不认为这个项目是为java8环境创建的，是吗？ 如果不是我该怎么办？

那么appengine-maven-plugin错误呢？ 我怎么解决这个问题？ 为什么我看到这个， Cloud SDK有什么问题吗？ 或者还有其他原因。

Answer 1

如下所示：

  1.7 1.7 UTF-8  

这是Java 7，因此，如果要使用Java 8运行它，则必须将外观更改为1.7到1.8。

appengine-maven-plugin的错误是你试图使用Java 7，同时说命令中使用Java 8。
