How to simply download a JAR using Maven?

Question

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

Answer 1

You can use:

mvn dependency:copy -Dartifact=<group>:<artifact-name>:<version> -DoutputDirectory=/tmp/my_custom_dir

(Replace <values> with the ones of your case)

That's the full documentation of the goal: https://maven.apache.org/plugins/maven-dependency-plugin/copy-mojo.html

Note: the other "dependecy:get" way of doing this has been deprecated.

Answer 2

See How to use Maven pom to download jar files only. This worked really nicely for me.

My use case was that I wanted to download some of the dependency jars to deploy to a QA server, and was doing it manually (outside of the Maven build). I'm not sure exactly what your use case is.

Answer 3

You can download Jar package to specific directory.

mvn dependency:get -Dartifact=org.riversun:random-forest-codegen:1.0.0 -Ddest=./

Answer 4

Go to http://mvnrepository.com. Search for the artifact you want to download, choose the version from the list of results and simply download the bundle.

Answer 5

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

Answer 6

It's possible to download a JAR from a Gitlab Maven private repository. The URL is appearing when running some Maven command so it's a bit hacky but it's working for me.

Like this:

wget --header "PRIVATE-TOKEN: ${GITLAB_PRIVATE_TOKEN}" "https://gitlab.com/api/v4/projects/${GITLAB_PROJECT_ID}/packages/maven/${MAVEN_PACKAGE_NAME}/${MAVEN_VERSION}/${JAR_FILE}"

Where,

• GITLAB_PRIVATE_TOKEN is a Gitlab Token with right "api" (atm the others are not enough)
  • GITLAB_PROJECT_ID e.g. 1462237
  • MAVEN_PACKAGE_NAME e.g. com/bar/foo
  • MAVEN_VERSION e.g. 0.0.1
  • JAR_FILE e.g. foo-0.0.1.jar
