How to install specific version of elasticsearch via brew

brew_elasticsearch.sh

brew tap homebrew/versions
brew cask install java
brew search elasticsearch
brew install [email protected]
brew services start [email protected]

I tried to install an older version from command:
apple$ brew install elastic/tap/[email protected]

However it returns an error:
Warning: No available formula or cask with the name "elastic/tap/[email protected]". Did you mean elastic/tap/elasticsearch-full?
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching for a previously deleted formula (in the last month)...
Error: No previously deleted formula found.

If I do:
brew search elasticsearch

It gives me existing versions in brew:
elastic/tap/elasticsearch-full ✔ elasticsearch@6
elasticsearch

Any solution on how to install older version of elasticsearch on MAC? Can we put an older version of Elasticsearch in brew through some package?

From the experiences of our company( big credit to our new college! ), the following should work:

1. Update brew

  brew update

2. Modify formula

  cd /usr/local/Homebrew/Library/Taps/homebrew/homebrew-core/Formula
  git checkout 5874ac8c8fab69f8a714d643581e489bcb176d92 [email protected]

3. Install [email protected]

  brew install openjdk@8
  brew install [email protected]

If you see the following error

Error: [email protected]: Unsupported special dependency :java

Remove or comment this line( around line 15) from [email protected]

depends_on :java => "1.8+"

4. Check version

  brew info [email protected]

5. Pin version

  brew pin [email protected]

This worked well for me, thanks @xofred!
