MC Mod Porter v1.2.0-beta

MC Mod Porter v1.2.0-beta

This beta introduces a desktop GUI while keeping the existing CLI available in the same cross-platform JAR.

What's new

• Added a Swing/FlatLaf desktop GUI that opens when the JAR is launched without arguments.
• Added project-folder browsing and automatic source-version and Fabric/NeoForge loader detection.
• Added target-version selection using MC Mod Porter's existing supported-version database.
• Added Port Mod, Build, and Run Client actions.
• Added live logs, status, and progress while porter and Gradle tasks run.
• Added Open Folder and Cancel controls.
• Kept the existing CLI behavior when command-line arguments are supplied.
• Removed the unused visual-tester and deep-debugger experimental modules.
• Updated the helper script so it finds the current release JAR instead of relying on an old hardcoded filename.

Download

• auto-porter-1.2.0-beta.jar — standalone GUI + CLI JAR
• auto-porter-1.2.0-beta.zip — packaged Windows distribution
• auto-porter-1.2.0-beta.tar — packaged macOS/Linux distribution
• SHA256 files are included for verifying each download.

The standalone JAR is the recommended download for most users.

Open the GUI:

java -jar auto-porter-1.2.0-beta.jar

Use the CLI:

java -jar auto-porter-1.2.0-beta.jar --help

Use an extracted mod source/project folder containing its Gradle files and src/ directory. Compiled mod JARs cannot be ported directly.

MC Mod Porter requires Java 21 or newer. Ported projects may require a newer Java version depending on their target Minecraft version.

Beta notice

This release is still beta software. Always review the generated project, logs, and port-report.json; some API or mod-specific changes may still require manual work.
