mvnw build a container image successful depsite of a Java exception thrown during build but where is the image created?

Describe the bug (Describe the problem clearly and concisely.) My environment: Windows 10 laptop, 64 bit 8 GB RAM Running Docker Desktop - allocated 2 CPUs and 3.75 GB (could not allocate 4GB or more - not enough memory) Using Windows Command Prompt to create a container image:

mvnw package -Pnative -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true

Build succeeded but an exception was thrown - why? And there is no image that I can see. Was it built correctly?

Hum, we need to fix this doc. It’s incorrect nowadays. I will fix it.

Hello @jaikiran https://github.com/jaikiran good spot! Not sure how you managed to deduce I used JDK 8 as there is no clear statement saying that, but I did use JDK 8. I was following an online tutorial which specified using JDK 8: https://quarkus.io/guides/building-native-image

Does anyone know how well is the backward compatibility of Java 11 to Java 8? Or is there an option to specifying using Java 8 native-image instead of the default Java 11?

I have other work related applications that run on Java 8 and obviously I want to be cautious to avoid breaking those from upgrading JRE.

Hello @jaikiran thanks for your reply. The -runner is the native executable. It is not the container image that I am looking for. I think I now understand why my mvnw package ... build did not create a container image now: I did not adding the required docker extension to my project before build!

Fixed: I first added quarkus-container-image-docker to my project by running below command: mvnw quarkus:add-extension -Dextensions="container-image-docker"

Then re-run the same build command as before:

mvnw package -Pnative -Dquarkus.native.container-build=true -Dquarkus.container-image.build=true
...
[INFO] [io.quarkus.container.image.docker.deployment.DockerProcessor] Built container image jackhu/quarkus-greeting-app:1.0-SNAPSHOT (26e11492d9b6)
...
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

The build created a new Docker container image as shown above: jackhu/quarkus-greeting-app:1.0-SNAPSHOT. The presence of the new image is also confirmed by querying my local Docker image repository:
