Maven Install Script

Installs Maven, SDKMAN! (if not installed), and needed dependencies.

Script status: Stable

OS support: Debian 9+, Ubuntu 18.04+, and downstream distros.

Maintainer: The VS Code and GitHub Codespaces teams

Syntax

./maven-debian.sh [Maven version] [SDKMAN_DIR] [Non-root user] [Add rc files flag]

Or as a feature:

"features": {
    "maven": "latest"
}

Argument	Feature option	Default	Description
Maven version	version	latest	Version of Maven to install. Specify latest to install the latest stable version.
SDKMAN_DIR		/usr/local/sdkman	Location to find SDKMAN!, or if not found, where to install it.
Non-root user		automatic	Specifies a user in the container other than root that will use Gradle. A value of automatic will cause the script to check for a user called vscode, then node, codespace, and finally a user with a UID of 1000 before falling back to root.
Add to rc files flag		true	A true/false flag that indicates whether sourcing the nvm script should be added to /etc/bash.bashrc and /etc/zsh/zshrc.

Usage

Feature use

To install these capabilities in your primary dev container, reference it in devcontainer.json as follows:

"features": {
    "maven": "latest"
}

If you have already built your development container, run the Rebuild Container command from the command palette (Ctrl/Cmd + Shift + P or F1) to pick up the change.

Script use

1. Add maven-debian.sh to .devcontainer/library-scripts

2. Add the following to your .devcontainer/Dockerfile:

   ENV SDKMAN_DIR="/usr/local/sdkman"
   ENV PATH=${SDKMAN_DIR}/bin:${SDKMAN_DIR}/candidates/maven/current/bin:${PATH}
   COPY library-scripts/maven-debian.sh /tmp/library-scripts/
   RUN apt-get update && bash /tmp/library-scripts/maven-debian.sh "latest" "${SDKMAN_DIR}"

That's it!
