We're creating the awaiter after calling open, yet open uses the awaiter.

Attached full maven debug logs for this issue.

Docker installed on my machine is through Docker Toolbox as I don't have enterprise'version of Windows 10 ( not sure if this can cause any issue)

Code for which i am trying to generate image can be found at https://github.com/rohit4j/spring-boot-cloud-native-docker

Windows Version: 1903 Build 18362.535
Docker(installed using Docker Toolbox) version: 19.03.1

Thanks, @rohit4j. Docker Toolbox should work, although it can be harder to get it set up correctly. Does it work when you take Spring Boot and Maven out of the picture? There are several suggestions in this Docker toolbox issue for making sure that //./pipe/docker_engine is available.
