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

java, maven

Solution

I know it was asked a year ago, but my answer might work for somebody other than me.

If creating the build tag in the `pom.xml` file not works, try editing the `settings.xml` file at your .m2 directory this way:

<pluginGroups>
  ...
  <pluginGroup>org.apache.tomcat.maven</pluginGroup>
  ...
</pluginGroups>

I found the solution here: http://tomcat.apache.org/maven-plugin-2.2/

Problem

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.

Do you have any solutions ? Thank you
