Manual Download, and install Maven plugin

Question

So I downloaded This plugin

http://mvnrepository.com/artifact/org.codehaus.mojo/cobertura-maven-plugin/2.5

How do I get it manually installed to maven ?

I've tried

maven -DartifactId=cobertura-maven-plugin -DgroupId=org.codehaus.mojo -Dversion=2.5 plugin:download

But get this error:

[WARNING] Cannot resolve plugin-mapping metadata for groupId: org.codehaus.mojo:
cobertura-maven-plugin:maven-plugin:2.5 - IGNORING.

Answer 1

use this command to download plugins so it also download also all the required dependencies:

mvn org.apache.maven.plugins:maven-dependency-plugin:2.6:get -Dartifact=groupId:artifactId:version

manually downloading plugins is asking for troubles and a lot of going back and forth to recover all the dependencies.

If you do not have the option, and must do it manually, use the command :

mvn org.apache.maven.plugins:maven-install-plugin:2.5.1:install-file ...

to install them.
