$ mvn jar:help $ mvn jar:help -Ddetail=true
If you need to use the plugin's coordinates instead of its prefix, you can do that as following:
$ mvn org.apache.maven.plugins:maven-jar-plugin:3.3.0:help $ mvn org.apache.maven.plugins:maven-jar-plugin:3.3.0:help -Ddetail=true
You can also use the goal describe of the help plugin to get information about the jar plugin and lists its goals:
$ mvn help:describe -Dplugin=jar $ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-jar-plugin:3.3.0" $ mvn help:describe -Dplugin="org.apache.maven.plugins:maven-jar-plugin:3.3.0" -Ddetail=true
The parameter goal gives information about a goal of the jar plugin:
$ mvn jar:help -Dgoal=jar -Ddetail=true $ mvn help:describe -Dplugin=jar -Dgoal=jar -Ddetail=true
