Quarkus: How to increase maximum heap space while building native images with Gradle?

Question

I am trying to build a native image of a Quarkus application with Gradle. I execute:

./gradlew build -Dquarkus.package.type=native -Dquarkus.native.container-build=true

It fails with the following error:

Execution failed for task ':my-service:quarkusBuild'.
> io.quarkus.builder.BuildException: Build failure: Build failed due to errors

  Caused by: java.lang.RuntimeException: Image generation failed. Exit code was 137 which indicates an out of memory error. Consider increasing the Xmx value for native image generation by setting the "quarkus.native.native-image-xmx" property

        ... 11 more

As it is suggested in the stack trace, I try setting quarkus.native.native-image-xmx by adding the following instruction to the build command:

-Dquarkus.native.native-image-xmx=8g

Unfortunately it keeps failing. In the Activity Monitor, I see that java process doesn't use much memory while building (less then 1GB) which means, the property doesn't get applied.

Question: How to increase the size of Heap Memory while building a Quarkus native image with Gradle?

I think if you try your build without the -Dquarkus.native.container-build=true it will assign the required memory, I think the issue is with the container, there is the "-Dquarkus.native.additional-build-args="-J-Dxxx." whch allows options to be passed directly to the vm https://www.graalvm.org/reference-manual/native-image/Options/ — Nigel Savage, Aug 30 '21 at 12:25
@NigelSavage I cannot build without `-Dquarkus.native.container-build=true`. This would work only on Linux (as far as I understand). For me it would fail with: `java.lang.RuntimeException: The native binary produced by the build is not a Linux binary and therefore cannot be used in a Linux container image. Consider adding "quarkus.native.container-build=true" to your configuration` — Sasha Shpota, Aug 30 '21 at 15:35
yes correct, what I was trying to convey is that possibly you need to try and pass parameters to the running container to tell it to use more memory — Nigel Savage, Aug 30 '21 at 15:50
-Dquarkus.package.type=native -Dquarkus.native.container-build=true -Dquarkus.native.additional-build-args=-J-Xmx6g not sure about the syntax going off the -J in the doc https://www.graalvm.org/reference-manual/native-image/Options/ — Nigel Savage, Aug 30 '21 at 16:00
You might need to increase the amount of memory that the VM Mac starts for Docker can use — geoand, Aug 30 '21 at 19:45
