How to simply download a JAR using Maven?

Question

How do I download JAR during a build in Maven script?

Answer 1

Maven does not work like that. Here's the closest you'll get to my knowledge:

mvn dependency:get -DremoteRepositories=http://repo1.maven.org/maven2/ \                    -DgroupId=junit -DartifactId=junit -Dversion=4.8.2 \                    -Dtransitive=false 

Note that all parameters except transitive are required.
Also note that Maven will download the jar to your local repository, and there's no sensible way (that I know of) to copy it to a local directory.

Reference:

• dependency:get

Answer 2

Or since 3.1, simply as mvn dependency:get -Dartifact=org.springframework:spring-instrument:3.2.3.RELEASE
