Oracle Graal Skills

Use this domain to build, configure, and troubleshoot GraalVM Native Image applications with Maven, Gradle, or the CLI.

How to Use This Domain

Start with the routing table below.
Read only the specific Native Image file needed for the task.
Prefer Native Build Tools for Maven or Gradle projects. Use the raw native-image workflow for simple Java files or direct CLI usage.

Category Routing

Topic	File
`native-image` CLI builds, options, classpath, modules, output names, binary type, optimization, URL protocols, monitoring, security	`graal/native-image/build-native-image.md`
Maven `native-maven-plugin`, Gradle `org.graalvm.buildtools.native`, build-tool tasks, plugin options, and native test routing	`graal/native-image/native-build-tools.md`
Missing reflection, JNI, resources, resource bundles, serialization, dynamic proxies, conditional metadata, and `reachability-metadata.json` layout	`graal/native-image/reachability-metadata.md`
Build failures, runtime failures, missing metadata symptoms, class initialization issues, memory issues, diagnostics, Maven activation issues, and where to route fixes	`graal/native-image/troubleshooting.md`

Key Starting Points

graal/native-image/build-native-image.md
graal/native-image/native-build-tools.md
graal/native-image/reachability-metadata.md
graal/native-image/troubleshooting.md

Common Multi-Step Flows

Task	Recommended Sequence
Build a Java class with Native Image	`native-image/build-native-image.md`
Configure a Maven or Gradle project for Native Image	`native-image/native-build-tools.md` -> `native-image/build-native-image.md` for flags
Fix missing reflection, JNI, proxy, resource, bundle, or serialization metadata	`native-image/reachability-metadata.md`
Diagnose build failures or runtime behavior differences	`native-image/troubleshooting.md` -> `native-image/build-native-image.md` -> `native-image/reachability-metadata.md` if metadata is involved
