Maven GAE archetype not working

Question

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:

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>

What the heck. I have no idea what it does. But it apparently works. Thanks. – Karel Bílek Mar 27 '13 at 05:58
@xybrek, keep an eye on next version of the plugin 1.7.6, there's a pull request so it may become available any day – ZiglioUK Mar 27 '13 at 22:56
@KarelBílek, thanks. If you look into the plugin's pom.xml, that might shed a light, basically they bumped the version of the GAE plugin to 1.5.1 but there's no GAE maven repo with that version for java, therefore the two numbers have decoupled, at least for this version – ZiglioUK Mar 27 '13 at 22:58
