🛠️ Build & Installation

This repository uses a template-based build system to generate version-specific Dockerfiles for multiple vendors.

1. Generate Dockerfiles

You can generate Dockerfiles for specific Java versions across all vendors using the master install.sh script.

# Make scripts executable
chmod +x install.sh && chmod +x */*.sh

# Generate for default versions (21 and 25)
./install.sh

# Generate for specific versions
./install.sh 8 11 17 21 25

Generated Dockerfiles will be located in the target/ directory, named as <vendor>_<os>_<version>.Dockerfile.

2. Manual Installation

If you want to generate Dockerfiles for a specific vendor only:

cd adoptium
./adoptium_install.sh 21 25

✨ Features

• Multi-Arch: Native support for x86_64 (AMD64) and aarch64 (ARM64).
• Modern Bases: Uses Debian Bookworm and Rocky Linux 9.
• Full UTF-8: Correct emoji and special character display.
• Dynamic Downloads: Always fetches the latest patch version directly from vendors.
