# What is Maven?

You can run a Maven project by using the Maven Docker image directly,
passing a Maven command to `docker run`:

### Linux

docker run -it --rm --name my-maven-project -v "$(pwd)":/usr/src/mymaven -w /usr/src/mymaven maven:3.3-jdk-8 mvn clean install

### Windows

docker run -it --rm --name my-maven-project -v "$(Get-Location)":C:/Src -w C:/Src maven:3.3-jdk-8-windows mvn clean install

## Building local Docker image (optional)

This is a base image that you can extend, so it has the bare minimum packages needed. If you add custom package(s) to the `Dockerfile`, then you can build your local Docker image like this:

### Linux

docker build --tag my_local_maven:3.6.0-jdk-8 .

### Windows

docker build -f Dockerfile.windows --tag my_local_maven:3-jdk-9-windows --build-arg WINDOWS_DOCKER_TAG=1803 .

Yow, a lot of duplicated content between images. Is there a straightforward way to share some of these steps?

Yes, I agree. I am not a super user with docker, so I am not aware of any tricks for sharing content. I based my implementation on the existing image setup.

Same here, we should not have a dozen copies of the same script.

Perhaps it would be better to refactor the repository layout to use a flat structure, so that any Dockerfile.* could freely COPY any resource file (perhaps just a temporary script to RUN and delete).

Yes, the mvn-entrypoint.sh is copied across the various image directories as well, this is because Docker doesn't support COPY from outside the current directory (and children) into the image. I'm sure there could be some refactoring to take that into account, but I didn't want to make that part of this changset.

Cleaning up an existing situation is indeed something that should be deferred to a separate PR. I mentioned this here because this PR introduces a lot of duplication.

Perhaps we could start by introducing a single directory with all the Windows images, and leave the Linux images untouched for now.
