Gradle nativeBuild does not work with Bellsoft Liberica NIK SDK

[lukas-krecan]

The documentation recommends to use Bellsoft Liberica NIK SDK but if you run ./gradlew nativeBuild you get

 No compatible toolchains found for request filter: {languageVersion=17, vendor=matching('GraalVM'), implementation=vendor-specific} (auto-detect true, auto-download true)

If I switch to grl SDK, it works

It would be nice to either fix the docs or the build.

I tried and it works for me. Please make sure you ran gu install native-image with Liberica NIK before since this is a per SDK command to run. Side note : nativeBuild is now deprecated in favor of nativeCompile.

Please let me know how it goes.

I did gu install native-image (I spent around an hour trying fixing it). Can you try to uninstall the grl? My suspicion is that Gradle looks for GraalVM vendor and if you have it installed, it just finds it.

[sdeleuze]

Yes we will, maybe the is something specific we should fine tune on https://github.com/graalvm/native-build-tools side.

Ok so short term we are going to disable toolchain support as implemented via graalvm/native-build-tools#164 on start.spring.io and document that as part of Spring Native 0.11.1, see related documentation.

Middle term, Gradle Toolchain support should be made more powerful to support native-image flavors of Java, you can follow gradle/gradle#18896 for more details. gradle/gradle#18028 is also kind of related.

At the moment, the documented workaround does not seems to work:

tasks.withType(org.graalvm.buildtools.gradle.tasks.BuildNativeImageTask).configureEach {
	disableToolchainDetection = true
}

I have asked NBT team feedback on this and will keep you informed.

[sdeleuze]

I think I understand why it does not work, and it looks like a NBT 0.9.8 bug from what I can say. I created graalvm/native-build-tools#183 and will try to see how fast we can get NBT 0.9.9 to fix it.

For now, with Gradle and Native Build Tools use GraalVM CE.

[sdeleuze]

The bug is now confirmed and fixed in Native Build Tools 0.9.9-SNAPSHOT.

I am waiting to know if a quick NBT 0.9.9 release is possible, in that case, we will disable by default Gradle toolchain for native compilation.

Otherwise, I will move that issue to Spring Native 0.11.2 milestone and document in 0.11.1 that Liberica NIK is not yet supported with NBT + Gradle (GraalVM CE should be used instead).
