如何在 gitlab-ci docker 中构建期间提取共享库？

Question

I have a simple gitlab-ci pipeline. Now I want to add a maven dependency to a library that I want to share between different projects, eg my main project defines:

<dependencies>
    <dependency>
        <groupId>my.projects</groupId>
        <artifactId>my-commons</artifactId>
        <version>1.0.0</version>
    </dependency>
</dependencies>

The my-commons is also a project in my gitlab .

Question: how can I trigger a mvn clean install into the ci-repository on that shared dependency during build of my main project?

This is my gitlab-ci from main project:

image: adoptopenjdk/maven-openjdk11

#TODO how to trigger a mvn clean install on my-commons?

test:
  stage: test
  script: mvn test -B

build:
  stage: build
  script: mvn package -B -Dmaven.test.skip=true
  artifacts:
    paths:
    - target/*.jar

deploy:
  stage: deploy
  script: ...

Sidenote: I know I could setup a local shared repository manager like nexus , but I'd like to avoid that and simply add the common dependency into the build process.

Answer 1

You can build your own image and use it at gitlab-ci.

Example of Dockerfile:

FROM adoptopenjdk/maven-openjdk11

RUN mvn clean install

# ... other stuff

after you'll build your image and push it to docker hub you can use it inside your gitlab-ci.
