Google App Engine - Maven plugin not found

I want to run maven in my app engine application. However, I get this exception:

Error resolving version for plugin 'org.apache.maven.plugins:gwt-maven-plugin' from the repositories [local (C:\Users\user.m2\repository), central (http://repo.maven.apache.org/maven2)]: Plugin not found in any plugin repository

Thats my maven file:

What should I add to make it run?

UPDATE

I am using this maven plugin because I get:

The output directory for the project should be set to /test/war/WEB-INF/classes

UPDATE 2

    <plugin>
        <groupId>org.codehaus.mojo</groupId>
        <artifactId>gwt-maven-plugin</artifactId>
        <version>2.5.1</version>
        <configuration>
            <webappDirectory>/test/war/WEB-INF/classes</webappDirectory>
        </configuration>
    </plugin>

My exception is the same:

The output directory for the project should be set to /test/war/WEB-INF/classes

You have not mentioned the group id or artifact id for your plugin and maven is trying to assume the groupid.

    <plugin>
      <groupId>org.codehaus.mojo</groupId>
      <artifactId>gwt-maven-plugin</artifactId>
      <version>2.5.1</version>
    </plugin>

References

  1. You can find gwt-maven-plugin available at central maven repo.
  2. Reference on how to use gwt-maven-plugin.
  3. Browse through Google teams pom sample for GWT+GAE app.

NOTE - I tested your pom.xml in a sample project and found no errors.
