如何使用gradle使GitLab CI发布Spring Boot JAR？

Question

I have a Spring Boot project that builds using a bootJar task in gradle. It produces a runnable ____-1.0-SNAPSHOT.jar file. Now, I want to leverage GitLab CI to build the JAR and make releases.

There didn't seem to be an obvious way to do the builds. I started looking at the researchgate gradle plugin . It seems promising but has a lot of assumptions.

What is the best way to get the release JARs out of GitLab CI?

Answer 1

There is couple of ways of getting released artifacts from gitlab ci pipeline.

1. Publish it to maven repository (private repository if it is propitiatory)
2. use gitlab job artifact functionality within pipeline so you can download it via gitlab web interface
3. build docker image from your pipeline and upload it to docker registry from pipeline

Here is the sample .gitlab-ci.yml which uses gitlab job artifacts functionality (assume gradle wrapper is used)

image: java:8-jdk

cache:
  paths:
    - .gradle/wrapper
    - .gradle/caches

build:
  stage: build
  script:
    - ./gradlew assemble
  # define path to collect artifacts
  artifacts:
    paths:
      - build/libs/*.jar
    expire_in: 1 week
  only:
    - master

Ruwanka provided a great answer, however I believe it is now a bit outdated. GitLab.com (and self-hosted) now supports hosted maven repositories as a native feature of their Premium tiers.

More information regarding how to deploy a java application (JAR, etc.) for private or public consumption can be found here:
