Polyglot Embedding Demo with GraalVM

Demonstration repository showing polyglot embedding with GraalVM using Maven and Gradle. It contains a simple Main and Test class to bootstrap a polyglot embedding project.

For demonstration showing polyglot native embedding with GraalVM using Maven, see the Native embedding Maven project located in the native-embedding subdirectory.

For more details on polyglot embedding please see the docs: https://www.graalvm.org/latest/reference-manual/embed-languages/

Setup

Download GraalVM and point the JAVA_HOME environment variable to it.

Maven Usage

Download Maven or import as Maven project into your IDE.

  • mvn package build using javac. Starting from GraalVM Polyglot API version 24.1.0, you can use mvn -Pisolated package to build with the native isolate version of a guest language. By default, only the native isolate library for the current platform is installed. To install native isolate libraries for all supported platforms, use mvn -Pisolated -Disolated.all.platforms package.
  • mvn test to run the tests
  • mvn exec:exec to run the application. Starting from GraalVM Polyglot API version 24.1.0, you can use mvn -Pisolated exec:exec to embed the native isolate version of a guest language.
  • mvn -Pnative package to build a native-image
  • mvn -Passembly package to build an uber JAR containing all dependencies using the Maven Assembly Plugin. The resulting JAR can be executed using java -jar embedding-1.0-SNAPSHOT-jar-with-dependencies.jar. We do recommend not using shading whenever possible.
  • mvn -Pshade package to build an uber JAR containing all dependencies using the Maven Shade Plugin. The resulting JAR can be executed using java -jar embedding-1.0-SNAPSHOT.jar. We do recommend not using shading whenever possible.

Please see the pom.xml file for further details on the configuration.

Gradle Usage

Download Gradle or import as Maven project into your IDE.

  • gradle build build using javac
  • gradle run to run the Main application
  • gradle test to run the tests
  • gradle nativeCompile to build a native-image
  • gradle nativeRun to run the native image

Please see the build.gradle.kts file for further details on the configuration.
