问题
I'm trying to use google app engine for simple spring based application with maven. I have found that there is maven archetype avaible for that kind of web application (without spring, but this I can add on my own): Maven GAE.
So I used the following command:
mvn archetype:generate -DarchetypeGroupId=net.kindleit -DarchetypeArtifactId=gae-archetype-jsp -DgroupId=com.example -DartifactId=form -DarchetypeRepository=http://maven-gae-plugin.googlecode.com/svn/repository
However, when i tried to use "mvn gae:run" it doesn't work and I don't know how to solve this missing requirement:

回答1:
Same as here.
Can you try this?
<properties>
<gae.version>1.7.5</gae.version>
<gae-runtime.version>1.7.5.1</gae-runtime.version>
</properties>
<plugin>
<groupId>net.kindleit</groupId>
<artifactId>maven-gae-plugin</artifactId>
<version>${maven.gae.plugin.version}</version>
<configuration>
<unpackVersion>${gae.version}</unpackVersion>
<serverId>appengine.google.com</serverId>
<appDir>${webappDirectory}</appDir>
</configuration>
<dependencies>
<dependency>
<groupId>net.kindleit</groupId>
<artifactId>gae-runtime</artifactId>
<version>${gae-runtime.version}</version>
<type>pom</type>
</dependency>
</dependencies>
</plugin>
