What is Maven?

Apache Maven is a software project management and comprehension tool.
Based on the concept of a project object model (POM),
Maven can manage a project's build,
reporting and documentation from a central piece of information.

How to use this image

Run a single Maven command

For many simple projects, you may find it inconvenient to write a complete Dockerfile.
In such cases, you can run a Maven project by using the Maven Docker image directly,
passing a Maven command to docker run:

docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3.9-jdk-7 mvn clean install

Reusing the Maven local repository

The local Maven repository can be reused across containers by creating a volume and mounting it in /root/.m2.

docker volume create --name maven-repo
docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will download artifacts
docker run -it -v maven-repo:/root/.m2 maven mvn archetype:generate # will reuse downloaded artifacts

Packaging a local repository with the image

The $MAVEN_CONFIG dir (default to /root/.m2) is configured as a volume so anything copied there in a Dockerfile at build time is lost.
For that the dir /usr/share/maven/ref/ is created, and anything in there will be copied on container startup to $MAVEN_CONFIG.

To create a pre-packaged repository, create a pom.xml with the dependencies you need and use this in your Dockerfile.
/usr/share/maven/ref/settings-docker.xml is a settings file that changes the local repository to /usr/share/maven/ref/repository,
but you can use your own settings file as long as it uses /usr/share/maven/ref/repository as local repo.

COPY pom.xml /tmp/pom.xml
RUN mvn -B -f /tmp/pom.xml -s /usr/share/maven/ref/settings-docker.xml dependency:resolve

To add your custom settings.xml file to the image use

COPY settings.xml /usr/share/maven/ref/

For an example, check the tests dir

Running as non-root

Maven needs the user home to download artifacts to, and if the user does not exist in the image an extra
user.home Java property needs to be set.

For example, to run as user 1000 mounting the host' Maven repo

docker run -v ~/.m2:/var/maven/.m2 -ti --rm -u 1000 maven mvn -Duser.home=/var/maven archetype:generate

Build the Image

If you wish to build the images yourself a set of docker-compose files have been
provided, one each for the different versions and os types.

To build the alpine linux jdk 8 image simply run

docker-compose -f docker-compose-alpine-jdk-8.yml build

Change the argument to -f for the relevant image you wish to build.
