'dockerBuildImage' task requires ECR credentials

Before applying the plugin, my team used dockerBuildImage task to build the image for local testing. After configuring deployment to ECR, this task suddenly starts to know about ECR and fails with

$ ./gradlew dockerBuildImage
> Task :populateECRCredentials FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':populateECRCredentials'.

BUILD FAILED in 4s

In my opinion it shouldn't - it's just about building the image, not pushing it to ECR. There are other tasks responsible for pushing. During building, everything apart from downloading needed Docker layers should happen locally.

A workaround is to comment out the plugin usage, then it works as before.

Best, Piotr
