How to simply download a JAR using Maven?

Question

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

Answer 1

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
