Parse & validate GraalVM metadata META-INF/native-image

[ljluestc]

Changes Made

Core Implementation:

• Created 5 new build items to carry parsed native-image metadata through the Quarkus build process:

  • NativeImagePropertiesBuildItem - for parsed command-line arguments from native-image.properties
  • NativeImageReflectConfigBuildItem - for reflection configuration JSON
  • NativeImageResourceConfigBuildItem - for resource configuration JSON
  • NativeImageJniConfigBuildItem - for JNI configuration JSON
  • NativeImageProxyConfigBuildItem - for proxy configuration JSON

• Implemented NativeImageMetadataParserStep - a new build step that:

  • Scans all dependencies for META-INF/native-image files
  • Parses native-image.properties files with complex argument handling (including quoted strings)
  • Validates JSON configuration files
  • Produces build items containing the parsed metadata

• Updated NativeImageBuildStep and NativeImageInvokerInfo.Builder to consume parsed metadata and inject arguments directly into the native-image command line

Testing:

• Added comprehensive unit tests for argument parsing logic and JSON validation
• Created integration test module native-image-metadata-parser that verifies:
  • JVM functionality (resource bundle access with different locales)
  • Native image compilation success with metadata injection
  • End-to-end functionality

Key Features:

• Automatic Discovery: Scans all dependency JARs for native-image metadata
• Smart Parsing: Correctly handles complex command-line arguments including quoted strings and spaces
• JSON Validation: Ensures configuration files contain valid JSON structures
• Error Handling: Proper logging and graceful handling of malformed metadata
• Backwards Compatibility: Maintains existing exclusion mechanisms as fallback

Thanks for the contribution.

Can you elaborate on why this is useful for Quarkus?
