Homebrew saying Xcode is outdated

I'm trying to perform an install of a package with Homebrew, but when I try to run the install I am getting the following error:

> Error: Your Xcode (7.3.1) is outdated. Please update to Xcode 8.0 (or delete it). Xcode can be updated from the App Store.

I would like to keep Xcode 7.3.1 on this machine since I have Xcode 8 on another machine, and am using this one for older projects.

I have found a similar post on SO, but the recommended solution to set export TRAVIS=1 doesn't seem to work for me. Hoping someone has a fix or a workaround I may use. Here are some more of my specifics:

Xcode 7.3.1
Homebrew 1.0.8-135-g4284b82
macOS Sierra 10.12 (16A323)

If anything other specifics needed, please let me know.

Thanks guys!

So as @NicolasMiari mentioned in a comment above, the fix to my issue ended up having to have both Xcode 7 and Xcode 8 on my machine. I went on the apple developer site, downloaded Xcode 8, saved it to my documents and then used:

sudo xcode-select -switch ~/Documents/Xcode.app/

and then ran my brew install which worked as expected. Afterwards I ran:

sudo xcode-select -switch /Applications/Xcode.app/

to switch back to Xcode 7.3.1.

Hope this helps someone else, and thanks for the suggestions.

Just do as this

Open the file /usr/local/Homebrew/Library/Homebrew/extend/os/mac/diagnostic.rb ,

then delete this line check_xcode_minimum_version in the following function.

def fatal_build_from_source_checks
	%w[
	  check_xcode_license_approved
	  check_xcode_minimum_version
	  check_clt_minimum_version
	  check_if_xcode_needs_clt_installed
	].freeze
	end

Then brew install works fine.

1. according to https://github.com/Homebrew/brew/issues/4957 outdated home-brew could cause this problem, brew update-reset fix it.

2. if step 1 does not work, reinstall homebrew with /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Renaming worked for me:

Xcode -> Xcode-old
Xcode-beta -> Xcode

Two options:

1. The best option is to update your xcode first, then follow @George H's recommendation above:

2. Set the xcode-select to the path of your CommandLineTools.

   sudo xcode-select --switch /Library/Developer/CommandLineTools
   

   As explained here, .Homebrew without Xcode

Both options work well.

Run this code in terminal

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null ; brew install caskroom/cask/brew-cask 2> /dev/null

Then try running below code,

brew install jenkins

Hope this solves
