Java Development on macOS

December 31, 2016

Back in the day I used to be a Windows guy, but when Vista came out I decided to jump ship and switch to Mac/OS X. I haven’t looked back since.

With the ability to run Windows and Linux on a Mac (either via VirtualBox or Boot Camp), I find I can do all I need on a Mac. This includes Java development which I would argue is much easier to install and manage on macOS than on a Windows box.

Here are some of the tools I use for Java development on the Mac.

Package Management

Homebrew is a package manager that lets you easily install command-line tools, applications and services on your Mac. This is one of the first things I install on any macOS machine. We’ll be using it to install everything else in this guide.

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

Homebrew Maintenance

I occasionally run the following commands to make sure my Homebrew installation is healthy and up to date.

$ brew update
$ brew doctor
$ brew upgrade
$ brew cleanup

Java Development Kit

We can’t really do Java development without the JDK installed, so let’s use Homebrew to do it.

$ brew cask install java

Could that be any easier? No license agreements. No installation wizards with multiple Next buttons. No PATH variables to edit. Just one command. Done.

Build Tools

It’s helpful to have two of the most popular Java build tools installed:

$ brew install maven
$ brew install gradle

Integrated Development Environment

I highly recommend IntelliJ IDEA as an IDE for Java development.

$ brew cask install intellij-idea

Version Control

Since we’re modern developers we use Git, and it’s important to ensure we have the latest version installed.

I also recommend SourceTree if you prefer a graphical Git interface.

$ brew install git
$ brew cask install sourcetree

Shell Tools

bash-it is a collection of bash scripts that provide a number of helpful aliases, completions and plugins for Java developers.

First we need to install bash-it:

$ git clone --depth=1 https://github.com/Bash-it/bash-it.git ~/.bash_it
$ ~/.bash_it/install.sh

Enable Relevant Aliases, Completion, Plugin

Now it’s time to enable a bunch of helpful aliases, completions and plugins:

$ bash-it enable alias git
$ bash-it enable alias maven
$ bash-it enable completion brew
$ bash-it enable completion git
$ bash-it enable completion gradle
$ bash-it enable completion maven
$ bash-it enable plugin git
$ bash-it enable plugin java

JavaDocs

Finally, finding and reading JavaDocs can be quite a pain. Google searches don’t always lead you to the latest version of the docs. Fortunately Dash makes it easy to get all the latest JavaDocs into one easy and consistent UI.

$ brew cask install dash
