Maven GAE原型不起作用

Question

我正在尝试将Google App
Engine与Maven一起用于基于Spring的简单应用程序。我发现有一种适用于这种Web应用程序的Maven原型（没有Spring，但是我可以自己添加）：Maven
GAE。

因此，我使用了以下命令：

mvn archetype:generate -DarchetypeGroupId=net.kindleit -DarchetypeArtifactId=gae-archetype-jsp -DgroupId=com.example -DartifactId=form -DarchetypeRepository=http://maven-gae-plugin.googlecode.com/svn/repository

但是，当我尝试使用“ mvn gae：run”时，它不起作用，而且我不知道如何解决此缺失的要求：

可以补充一点，我尝试使用不同版本的maven-gae-plugin，但没有成功…。

你可以试试这个吗？

<properties>
  <gae.version>1.7.5</gae.version>
  <gae-runtime.version>1.7.5.1</gae-runtime.version>
</properties>
