How can I download a specific Maven artifact in one command line?

Question

I can install an artifact by install:install-file, but how can I download an artifact?

For example:

mvn download:download-file -Dgroup

One could use dependency:copy (http://maven.apache.org/plugins/maven-dependency-plugin/copy-mojo.html) which takes a list of artifacts defined in the plugin configuration section and copies them to a specified location, renaming them or stripping the version if desired. This goal can resolve the artifacts from remote repositories if they don't exist in either the local repository or the reactor.

Not all the properties of the plugin could be used in maven CLI. The properties which have "User Property:" property defined could be specified. In the below example I am downloading junit to my temp folder and stripping the vesion from the jar file.

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:copy -Dartifact=junit:junit:4.11 -DoutputDirectory=/tmp -Dmdep.stripVersion=true

where artifact=junit:junit:4.11 is the maven coordinates. And you specify artifcat as groupId:artifactId:version[:packaging[:classifier]]
