Once you have Homebrew on your Mac, use the brew command to install OpenJDK, which is the open source way to write Java applications: $ brew cask install java If you haven't installed it yet, Matthew Broberg's Introduction to Homebrew walks you through the steps. Homebrew is the de-facto standard package manager for macOS. (If you are running Linux, please see Seth Kenlon's article How to install Java on Linux.) Install OpenJDK from a Brew repository So I will walk through installing and getting started with the Java development environment on macOS. This future for Java development starts with more people installing and using Java. Luckily, new Java frameworks (e.g., Quarkus, Micronaut, and Helidon) have recently broken through the challenges by offering smaller applications that compile faster and are designed with distributed systems in mind. Other languages filled in the space, particularly JavaScript, Python, and Go, with Rust and WebAssembly offering new alternatives.ĭespite this competition, cloud-native Java is making an impact on cloud-centric software development. Unfortunately, those efforts weren't good enough to make Java the preferred programming language for developers to implement cloud-native Java applications for serverless and event-driven platforms.

With these technologies, the Java application stack has been optimized to run larger heaps and highly dynamic frameworks that can make decisions at runtime.

This could have saved me a few extra minutes of my day. I guess this is just a friendly reminder for me to always read my logs. If you need to have first in your PATH, run:įor compilers to find you may need to set: Sudo ln -sfn is keg-only, which means it was not symlinked into /opt/homebrew,īecause this is an alternate version of another formula. => Caveatsįor the system Java wrappers to find this JDK, symlink it with

In gathering up material for this post, I discovered that the solution to this just happened to be buried in the caveats that were logged during installation. With the symlink in place, IntelliJ detects the installation as expected. $ sudo ln -s /Library/Java/JavaVirtualMachines This was a very easy fix to put in place.

Selecting the Project SDK dropdown did not give me the option to use the JDK I just installed.Īfter digging around a bit, I discovered that this is because brew may not symlink the JDK installation to /Library/Java/JavaVirtualMachines. However, I noticed that IntelliJ did not auto-detect the Java installation when creating new projects. $ brew install brew install intellij-idea-ce

I recently went through a Homebrew (brew) Open JDK 11 and IntelliJ IDEA installation on a new Macbook Pro.
