The method here is described in terms of using a command line. You can easily do this on linux or in a Terminal window in macOS. You can do it in Windows.
We recommend obtaining an OpenJDK JDK 11 from AdoptOpenJDK: https://adoptopenjdk.net/?variant=openjdk11&jvmVariant=hotspot, either the Installer or .zip/.tar.gz variants whichever you prefer (if you’re not sure, choose the Installer).
gradle and gitYou should be able to install the latest (or close to the latest) versions of gradle and git using your OS package manager.
For macOS we recommend using brew, which can be installed following the instructions at https://brew.sh/. After installing brew, open a Terminal window and type in (using an Administrator privileged user): brew install gradle git or brew upgrade gradle git if you already have them installed but need to upgrade the version.
For linux this will depend on which distribution you’re using. For debian based distributions (e.g. Mint, Ubuntu, Debian) run sudo apt-get install gradle git whilst for RPM-based distributions run (probably) sudo yum install gradle git If you have some other version of linux you’ll probably be able to work it out!
For Windows users, you might do well by using the Chocolatey package manager. See install instructions at https://chocolatey.org/, and you will just need choco install gradle git Alternatively, you could install a real bash shell and install both gradle and git through apt-get. Another alternative would be to install them separately following the instructions at https://gradle.org/install/, and for git here are a couple of suggestions: Git for Windows https://gitforwindows.org/ or a real bash-shell https://devblogs.microsoft.com/commandline/bash-on-ubuntu-on-windows-download-now-3/ !
