Maven - No plugin found for prefix 'tomcat7' in the current project

Question

I've created a Maven project with the archetype "webapp" but when I start the command "mvn tomcat7:start", I've the following error :

No plugin found for prefix 'tomcat7' in the current project and in the plugin groups [org.apache.maven.plugins, org.codehaus.mojo] available from the repositories [local (C:\dark\.m2\repository), central (http://repo.maven.apache.org/maven2)] -> [Help 1]
[ERROR] 
[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.

My project structure :

-src 
   -main
       -resources
       -webapp
          -WEB-INF
             -web.xml
          -index.jsp
-target
    -classes
    -dependency
        - // the 'dependency' directory contains all the jar files
    -lbagno
    -maven-archiver
    -surefire
    lbagno.war

My pom.xml contains well the dependency for tomcat.

pom.xml

         <type>maven-plugin</type>
     </dependency>
 </dependencies>

 <build>
    <finalName>lbagno</finalName>
 </build>

</project>

I don't understand why it doesn't work.

Do you have any solutions ?

Thank you

Try to delete this part from your dependency and put this line of code in plugins on your projects pom.xml. From dependency delete this line of codes:

  <dependency>
     <groupId>org.apache.tomcat.maven</groupId>
     <artifactId>tomcat7-maven-plugin</artifactId>
     <version>2.2</version>
     <type>maven-plugin</type>
 </dependency>

and put this in ....

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
</plugin>

This will surely work.
