A simple wrapper around GraalVM tooling that will download and locally cache a GraalVM installation and make available select parts of the GraalVM compiler for use in Gradle builds.
To use this plugin, apply com.palantir.graal. See a full example in the
ETE tests.
./gradlew nativeImage: create a native image using GraalVM's native-image tool with the configuration as specified
by the graal Gradle extension. Outputs are produced to ${projectDir}/build/graal/.
./gradlew sharedLibary: create a shared library using GraalVM's native-image tool with the configuration as specified
by the graal Gradle extension. Outputs are produced to ${projectDir}/build/graal/.
Configure this plugin and its wrappers around GraalVM tools through the graal extension with the following options:
General GraalVM controls
graalVersion: the version string to use when downloading GraalVM (defaults to19.0.2)downloadBaseUrl: the base download URL to use (defaults tohttps://github.com/oracle/graal/releases/download/)
native-image controls
outputName: the name to use for the image outputmainClass: the main class entry-point for the image to runoption: additional native-image optionshttps://github.com/oracle/graal/blob/master/substratevm/OPTIONS.md
We maintain a number of different repositories, and rather than re-download tooling and cache it per repository, this
plugin maintains a central cache in the user's home directory (~/.gradle/caches/com.palantir.graal). Tooling artifacts
are cached by version, so multiple projects referring to different GraalVM versions will not corrupt the cache.
No locking is performed to check the atomicity of changes to the cache, so users should not expect this plugin to be well behaved when populating the cache from parallel processes.
Contributions are welcome. For larger feature requests or contributions, we prefer discussing the proposed change on a GitHub issue prior to a PR.
