native-helper-maven-plugin

Maven plugin with helper methods for generating native configuration

This maven plugin allows generation of graalvm metadata using the native-helper-graalvm

1. mojo 'generate'

Write a native-helper-config.yaml configuration file for the project. (configuration reference here)

<plugin>
    <groupId>org.fugerit.java</groupId>
    <artifactId>native-helper-maven-plugin</artifactId>
    <version>${native-helper-maven-plugin-version}</version>
    <executions>
        <execution>
            <id>generate-native-configuration</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>generate</goal>
            </goals>
            <configuration>
                <nativeHelperConfigPath>src/main/config/native-helper-config.yaml</nativeHelperConfigPath>
                <reflectConfigJsonOutputPath>${project.build.directory}/generated-resources/reflect-config-demo.json</reflectConfigJsonOutputPath>
                <warnOnError>true</warnOnError>
            </configuration>
        </execution>
    </executions>
</plugin>

mojo 'generate' configuration reference

name	default	required	type	description
nativeHelperConfigPath	none	true	string	Path to native-helper-config.yaml configuration file
reflectConfigJsonOutputPath	none	false	string	generation path for reflect-config.json file
createParentDirectory	false	false	boolean	if set to true will create reflectConfigJsonOutputPath parent folder
warnOnError	false	false	boolean	if set to true exception will be logged instead of generating a build error

2. mojo 'merge'

<plugin>
    <groupId>org.fugerit.java</groupId>
    <artifactId>native-helper-maven-plugin</artifactId>
    <version>${native-helper-maven-plugin-version}</version>
    <executions>
        <execution>
            <id>merge-native-configuration</id>
            <phase>prepare-package</phase>
            <goals>
                <goal>merge</goal>
            </goals>
            <configuration>
                <reflectConfigJsonFiles>
                    <reflectConfigJsonFile>${project.build.directory}/generated-resources/reflect-config-demo.json</reflectConfigJsonFile>
                    <reflectConfigJsonFile>${project.basedir}/src/main/config/reflect-config-nhg.json</reflectConfigJsonFile>
                </reflectConfigJsonFiles>
                <reflectConfigJsonOutputPath>${project.build.outputDirectory}/META-INF/native-image/reflect-config.json</reflectConfigJsonOutputPath>
                <createParentDirectory>true</createParentDirectory>
                <warnOnError>true</warnOnError>
            </configuration>
        </execution>
    </executions>
</plugin>

mojo 'merge' configuration reference

name	default	required	type	description
reflectConfigJsonFiles.reflectConfigJsonFile	none	true	string	List of reflect-config.json files to merge
reflectConfigJsonOutputPath	none	true	string	generation path for reflect-config.json file
createParentDirectory	false	false	boolean	if set to true will create reflectConfigJsonOutputPath parent folder
warnOnError	false	false	boolean	if set to true exception will be logged instead of generating a build error
