This docker container is our default build container for java based applications. It should be used to compile java projects with maven
Check out your Java project containing the maven build file. Run the container to start the maven compilation. You mount the root directory of your project into the container and call maven install:
docker run --name maven -v $PWD:/build -v /maven-repo maven-build install
This will mount your current working directory into "/build" of the container
call mvn install in that directory. Additionally the /maven-repo directory inside
the container will be persistet. Thus on subsequent runs of this container it will
likely reuse downloaded artifacts.
The downloaded artifacts are stored in a folder called "/maven-repo". If you don't want that, then you can override the maven environment by passing a different or empty MAVEN_OPTS to the command:
docker run --name maven -v $PWD:/build -e "MAVEN_OPTS=-Dmaven.repo.local=/build/local-maven-repo" maven-build install
Subsequent build can then be called via:
docker start -a maven
This will start the original container with the very same parameters and execute the build again. In that run, the downloads that have been cached before in /maven-repo are used and speed up the build.
