Hey everyone, I’m facing an issue with building my Micronaut application in CircleCI. It’s a Micronaut 2.5.4 application with Picocli and uses Java 11.
The build step that is failing on CircleCI is ./gradlew dockerBuildNative . I’m able to run the command and build a GraalVM native Docker image on my local computer fine. On CircleCI the output is as follows:
Step 7/11 : RUN native-image -H:Class=thub.event.scheduler.ThubEventSchedulerCliJobCommand -H:Name=application --no-fallback -cp /home/app/libs/*.jar:/home/app/resources:/home/app/application.jar

My CircleCI job and the full output can be seen here
It did successfully build once on CircleCI out of the nearly 20 times it has run; it’s not clear to me why the job succeed that one time it did.
I’m hoping someone else has a Micronaut application that they are successfully building with dockerBuildNative on CircleCI and they can point me to the right environment variables and/or Docker image to use on CircleCI (I’m currently using cimg/openjdk:11.0).
From the searching I have done, it looks like I need to increase the socket timeout on the underlying docker-java calls but it doesn’t appear there’s any way to do it that I know of. There was a request in 2016 to add an enhancement to the gradle-docker-plugin to be able to specify those timeouts.
