How do I download a Maven artifact at the command line without using dependency:get or maven-download-plugin?

Question

I'd like to download an artifact and its dependencies at the command line. I.e.

mvn [some plugin]:[goal] -DartifactId=[artifactId] -DgroupId=[groupId] -Dversion=[version]

I've tried mvn dependency:get but this seems to require a list of remote repositories. I want mvn to use what's already specified in settings.xml

I've also tried the maven-download-plugin but this doesn't seem to work properly (it tried downloading xerces-impl as a transitive dependency of ant and failed to resolve it. Neither xerces-impl nor ant are dependencies of my artifact).

Your help would be appreciated.

Answer 1

The copy goal is more appropriate here and it lets you specify an output directory as well (which is deprecated in the get goal):

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:copy -Dartifact=groupId:artifactId:version[:packaging][:classifier] -DoutputDirectory=[target] -Dmdep.useBaseVersion=true

mdep.useBaseVersion=true will remove timestamps from snapshot builds.

Answer 2

Try using the latest version of dependency:get, it works for me

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get -DartifactId=[artifactId] -DgroupId=[groupId] -Dversion=[version]

works for me

Example to download version 6.9.4 of TestNG to your local ~/.m2/repository (uses maven-dependency-plugin:get):

mvn org.apache.maven.plugins:maven-dependency-plugin:RELEASE:get \
-Dartifact=org.testng:testng:6.9.4:jar

Example to download version 4.11 of JUnit to your current working directory (uses maven-dependency-plugin:copy):

mvn org.apache.maven.plugins:maven-dependency-plugin:RELEASE:copy \
-Dartifact=junit:junit:4.11:jar

Answer 4

The simplest solution would be to create a simple pom with the appropriate dependencies and do mvn clean package on that mini project...

Answer 5

this is the method that I use, matches your need but less typing and brain cell consumption:

curl https://start.spring.io/starter.tgz | tar -xzvf -

(btw, you can add -d dependencies=lombok when the dependency you want is listed on starter like lombok.)

And then, in vim pom.xml, delete whatever parent and modify everything between dependencies. you just need to fill in group, artifact and version.

Finally, mvn package. It starts to download...
