Setup custom CodeBuild environment with Amazon ECR
Since faster Java development by Oracle, every tool we use these days need to follow up for every Java release or just support only LTS versions like Amazon. CodeBuild is AWS-hosted tool for building software applications and 3 months after stable Java 11 release still it does not support anything newer than Java 9. Time is up, now we will build our own build environment which will support Java 11 and Java 12 in future right after stable release.
