System requirements

Before installing JavaOptionsCli, ensure your system meets the following requirements:
  • Debian-based Linux distribution (Ubuntu, Debian, Linux Mint, etc.)
  • sudo privileges for installing Java versions and managing update-alternatives
  • Go 1.25.5 or later (only if building from source)
JavaOptionsCli uses the update-alternatives system to manage Java versions, which is standard on Debian-based distributions.

​
Option 2: Build from source

Make it globally available

You have two options to make JavaOptionsCli accessible from anywhere on your system:Move the binary to a directory in your system PATH:
sudo mv JavaOptionsCli /usr/bin/JavaOptionsCli
