Print "RUN echo" messages when building images

[claudio4j]

Hi, we are building local images as described in Creating images on-the-fly doc

we have a couple of RUN echo "Using product $PRODUCT_VERSION version from $REPO/$REF" in our Dockerfile

Dockerfile excerpt

ARG PRODUCT_VERSION=default
ARG REPO=main
ARG REF=xyz

RUN echo "Using product $PRODUCT_VERSION version from $REPO/$REF"

We also use .withBuildArg("PRODUCT_VERSION", params.getProductVersion()) to feed the appropriate parameters.

We enabled DEBUG level to org.testcontainers and com.github.dockerjava.api.command log categories.

But the RUN echo messages are not displayed in the build log, do you know what configuration is required to log them ?

Currently there is a failure with returned a non-zero code: 1

Caused by: com.github.dockerjava.api.exception.DockerClientException: Could not build image: The command '/bin/sh -c source ~/.bashrc     && if [[ "$PRODUCT_VERSION" == "default" ]] ;     then my-app install $REPO/$REF ;     else my-app install     -Dmyapp.version=$PRODUCT_VERSION     $REPO/$REF ; fi' returned a non-zero code: 1

The debug RUN echo and the actual docker build log would help track the error.
