Newest version of HomeBrew, versions no longer supported I am having problems installing the old version of grails on my mac, with homebrew.

The spot where I get stuck is at the brew versions grails as it will say that versions is no longer used.
I have executed brew tap homebrew/versions but the versions command do still not work.
How in the newest version of brew can I install Grails 2.3.5?

Error: The `versions` command is no longer supported.
You can use the homebrew-versions tap instead:
  https://github.com/Homebrew/homebrew-versions
Or use `brew log` to browse the git history.
brew tap homebrew/versions


then:

brew install homebrew/versions/grails23


brew search grails will show you all the available ones to install.
