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:
