java-to-native

CI plugin to convert a java program into a graalvm native image.

Plugin config

The following parameters can be set to configure the plugin.

• debug - Flag to enable debug logs. Optional, by default, debug logs are disabled
• jar_name - Executable jar file to convert into native binary
• config_file - Path to a yaml configuration file
• classpath - Path containing class files and jars to use as class path. Defaults to build/libs/*:build/classes
• reflection_path - Path to the reflection configuration if it already exists. If not specified, it will be generated at build/native/graal-config/

Usage

Docker

Execute from the working directory:

docker run --rm \
  -v path/to/jar:/work \
  -w=/work \
  -e PLUGIN_JAR_NAME=/work/build/native/libs/YamlValidator.jar \
  -e PLUGIN_CONFIG_FILE=/work/config/graal.yml \
  devatherock/java-to-native:1.0.0

native-image config

A YAML configuration file can be provided to supply additional arguments to the native-image command and to specify a list of arguments with which to run the main class or the jar to generate reflection config

Sample

native-image:
  build:
    # Additional arguments to pass to the native image build
    additional-args:
      - "-H:IncludeResourceBundles=net.sourceforge.argparse4j.internal.ArgumentParserImpl"
    # If specified, only these arguments will be passed to the image build
    #override-args:
    #  - "--no-server"
  agent:
    args:
      - ['--debug', 'false', '--path', 'src/test/resources/data/valid']
      - ['--debug', 'false', '--path', 'src/test/resources/data/invalid']
      - ['--debug', 'false', '--path', 'src/test/resources/data/invalid2']
      - ['--debug', 'true', '--path', 'src/test/resources/data/valid']
      - ['--debug', 'true', '--path', 'src/test/resources/data/invalid']
      - ['--debug', 'true', '--path', 'src/test/resources/data/invalid2']
      - []
      - ['--help']
