Using 3rd party plugins in maven

tomcat-plugin can be download from
http://www.codeczar.com/maven.

I did this manually, because when I ran the command

"maven-DartifactId=maven-tomcat-plugin -DgroupId=codeczar-tomcat -Dversion=1.2.1plugin:download"

what downloaded was just a broken file named"maven-tomcat-plugin-1.2.1.jar"(28kb).
[or, google the jar file to find the correct repository]
