GraalVM Reachability Metadata Repository

      

This repository contains reachability metadata for JVM libraries and frameworks, enabling them to work out of the box with GraalVM Native Image.

The GraalVM Gradle Plugin and GraalVM Maven Plugin automatically use the reachability metadata from this repository, so most projects do not need to configure it directly.

[!TIP] Missing metadata for a library you depend on? Run the Native Build Tools task in your project to detect the gap and automatically open an issue here.

Gradle

./gradlew listLibrariesMissingMetadata -PcreateIssues=true

Maven

./mvnw native:list-libraries-missing-metadata -DcreateIssues=true

🔎 Check if Your Library Is Supported

To quickly check whether reachability metadata exists for a specific library, run this command directly from your terminal:

curl -sSL \
  https://raw.githubusercontent.com/oracle/graalvm-reachability-metadata/master/check-library-support.sh \
  | bash -s "<groupId>:<artifactId>:<version>"
