Unable to install java8 with homebrew

Question

Installing java8 with Homebrew seems to no longer be working. After running:

brew install caskroom/cask/java8

I get the follow

Answer 1

Although cask remove the support for JAVA8, we can still install JAVA8 using brew.

It requires the manual download of JAVA8.dmg and add the java8.rb which could be used by cask.

Machine: MAC

OS: Mojave (10.14.6)

JAVA version: java 8u231

Step-1

Download dmg file from Oracle Site. You require oracle account to download the same

Step-2

Start the HTTP server from the folder where you downloaded the dmg file. For me it's ~/Downlaods and I use python to start HTTP server:

python -m SimpleHTTPServer 8000

Step-3

Create file java8.rb in /usr/local/Homebrew/Library/Taps/homebrew/homebrew-cask/Casks (where java.rb exist) and add the following:

cask 'java8' do
  version '8u231,b15:9eef341qase34d44fbaa21'
  sha256 'f808d11b34fa9ee7b6326b5b6dd18544496e02c84b839d94e062bd4493df5d45'

  url "http://localhost:8000/jdk-#{version.before_comma}-macosx-x64.dmg",
      cookies: {
                 'oraclelicense' => 'accept-securebackup-cookie',
               }
  name 'Oracle Java 8 Standard Edition Development Kit'
  homepage 'https://www.oracle.com/technetwork/java/javase/overview/index.html'

  depends_on macos: '>= :yosemite'

  pkg 'JDK 8 Update 231.pkg'

  uninstall pkgutil: "com.oracle.jdk#{version.before_comma}",
            delete:  [
                       '/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin',
                       '/Library/PreferencePanes/JavaControlPanel.prefPane',
                     ]

  zap trash: [
               '~/Library/Application Support/Oracle/Java',
               '~/Library/Application Support/com.oracle.java.JavaAppletPlugin.plist',
               '~/Library/Application Support/com.oracle.javadeployment.plist',
             ]

  caveats do
    license 'https://www.oracle.com/technetwork/java/javase/terms/license/javase-license.html'
  end
end

Step-4

Now, install using brew:

brew cask install java8

Note: I got the SHA-256 checksum from the above mentioned java download link.
