SimpleKotlin

Kotlin + Gradle starter. Builds a fat jar or a GraalVM native binary, and logs the way Minecraft does (SLF4J + Log4j2).

Build & run

Needs JDK 17+.

./gradlew build
java -jar build/libs/SimpleKotlin.jar

Native image

Needs GraalVM with GRAALVM_HOME set. On Windows you also need the Visual Studio Build Tools.

./gradlew nativeCompile
./build/native/nativeCompile/SimpleKotlin

If a library you add uses reflection, run the jar once with the tracing agent and copy what it finds into src/main/resources/META-INF/native-image/:

$GRAALVM_HOME/bin/java -agentlib:native-image-agent=config-output-dir=agent-out -jar build/libs/SimpleKotlin.jar
