Issue
I have multi module Maven project. Each module has its own Git repo.
According to GitLab documentation each module must have .m2/settings.xml
file for CI/CD via .gitlab-ci.yml
to work.
I would like to avoid having same .m2/settings.xml
file in each module.
Is there a way to achieve that?
Solution
There are several ways for achieving this
Hosting the settings.xml on a webserver
You could simply serve the settings.xml via a web server andwget
it during your CI/CD process.Clone the file via GIT
You can, as you already suggested, clone the file from one of the submodule repositories. There are ways for only retrieving parts of a repository, as discussed in this questionUsing a custom docker container with the correct Maven configuration You could create your own docker container image to use during your CI/CD process. This image could use the current image as base image (i.e. via Docker's
FROM
instruction) and add your own custom settings.xml directly to the .m2 directory. Or to any directory you want.
This would likely be the most elegant solution, however also the one that requires the most setup work. See this resource for how to use docker images from private container registries during GitLab CI/CD.- Obviously, you could also just copy the file to each of the repositories
