Java Install Script

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

Script status: Stable

OS support: Debian 9+, Ubuntu 16.04+, and downstream distros.

Maintainer: The VS Code and GitHub Codespaces teams

Syntax

./gradle-debian.sh [Java version] [SDKMAN_DIR] [Non-root user] [Add rc files flag]
Argument Default Description
Java version lts Version of Java to install. Specify lts to install the LTS 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

  1. Add java-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/java/current/bin:${PATH}
COPY library-scripts/java-debian.sh /tmp/library-scripts/
RUN apt-get update && bash /tmp/library-scripts/java-debian.sh "lts" "${SDKMAN_DIR}"

That's it!
