[ERROR] Failed to execute task "build-img:build": API error (500): {"message":"Cannot locate specified Dockerfile: Dockerfile.build"}

Yes. It's on win10-pro.

It happens when the context: is a relative path. I've tried with an absolute path, too, but got this:

[ERROR] Failed to execute task "build-img:build": API error (500): {"message":"Error parsing reference: \"<project-name>-build:<project-name>-<ad_domain>\\\\<username>\" is not a valid repository/tag: invalid reference format"}

Since my employer uses AD, my username causes a syntax error in the image name. That is a separate issue, though.

@willseward #70 changes how repo:images:tag are managed. Can you build master from source and give it a go? Had to google AD, i knew there was some letters missing. lol

Same issues on master.

I opened #76 to track the domain user issue.
