Automatic Schema Extraction

This extension includes a Rust-based schema extractor that generates JSON Schema directly from Amper's Kotlin source code. This ensures the schema is always up-to-date with Amper's latest version.

To update the schema when Amper is updated:

npm run extract-schema

Alternatively, use the building script:

cd tools/schema-extractor
./build.ps1

See Schema Extraction Guide for details.

Requirements

• Amper installed in your project (via wrapper scripts)
• JDK (automatically provisioned by Amper)
• Rust (optional, only needed to rebuild the schema extractor)

Extension Commands

• Amper: Check Version - Display the current Amper version
• Amper: Initialize Project - Create a new Amper project
• Amper: Convert Maven Project - Convert a Maven project to Amper
• Amper: Update Amper - Update the Amper wrapper
• Amper: Clean Shared Caches - Clean global Amper caches
• Amper: Clean Bootstrap Cache - Clean JRE/distribution caches
• Amper: Show JDK Info - Display JDK information
