Java is Required for 'brew install'

[Adam Hill]

It is alarming Java is required to install from 'brew'

~ brew install git-credential-manager
git-credential-manager: Java 1.6+ is required to install this formula.
JavaRequirement unsatisfied!
You can install with Homebrew Cask:
brew cask install java
You can download from:
https://www.oracle.com/technetwork/java/javase/downloads/index.html

At least the brewd version is OpenJDK :-) Is this intended or a hanging requirement?

[Michael Novak]

Do you have a version of Java installed outside of Homebrew?

[John Briggs]

I'd recommend trying GCM Core's macOS preview release which does not have this requirement.
