When running our test suite for the first time on an Apple M1, we have to identify the Docker containers that fail to start. # J 546 c2 (Ljava/lang/String )Ljava/lang/AbstractStringBuilder If we try to run this Docker image on our arm64 Apple M1 machine, we get the following warning: It only comes with support for 圆4 machines. The example above is a screenshot of the official Keycloak Docker image. We can identify the available platforms by looking at the OS/Arch column on Docker Hub for a particular Docker image: When it comes to running our integration tests that use Testcontainers, the first thing we stumble over with our M1 machine are potential test failures because of missing arm64 platform support.ĭocker images are built for specific processor architectures. Integration Tests with Docker and Testcontainers To further verify the compatibility and optimization for various other tools for Apple's M1, checkout out isapplesiliconready. Only try to get the 圆4 build running if there's no arm64 build available (yet). Rule one: Whenever there's a native arm64 build of any development tool for the M1, go for it. But having worked with it for almost a year now, many have been continuously fixed.Īll other development tools that we use on a daily basis either provide an arm64 build or the emulated 圆4 version works fine: IntelliJ IDEA, Visual Studio Code, Eclipse, Slack, Notion, Docker for Mac, Spotify, Firefox, Microsoft Teams, Postman.

In the early days, there were some minor issues.

Installing a recent Docker for Mac version comes with Apple M1 support. However, we may run into issues and/or won't get the expected performance. With Apple's Rosetta 2 emulation, we can also try to work with an 圆4 JDK build. For managing different Java versions, sdkman or jEnv is an excellent option.įor those lucky developers that have the chance to work and experiment with the GraalVM, the support for Apple M1 has also landed. The brew formula for openjdk is also installing a compatible Apple M1 JDK build.

Eclipse Temurin (Adoptium project, former AdoptOpenJDK).

28 + 13 - CA ( build 17 + 35 - LTS, mixed mode, sharing )Īpart from the Azul Zulu JDK, many other JDK vendors have followed and now offer an arm64 build: Once we've downloaded and installed a compatible JDK build, we have the baseline for our Java development for our Apple M1: There's no difference in the installation process of a JDK compared to an 圆4 Mac. While searching for a arm64 compatible JDK back in 2021, the Azul Zulu JDK build popped up first.

The first thing we install as Java developers on a new machine is a JDK. I'll refer to the traditional Intel/AMD processors as 圆4 (you may find the following synonyms: x86_64, amd64).

Note: Throughout this article, both arm64 or aarch64 refer to the Apple M1 chip. This article will share my initial pitfalls when working with the Apple M1 and a collection of valuable tricks and workarounds for developing and testing Java applications. To solve those problems (not my main intent, but I told myself so) and experience if that processor is really that fast, I decided to buy the MacBook Pro. I was first shocked to encounter hardware incompatibilities in 2021. I had my first contact with the Apple M1 when one of my course students raised an issue that the build doesn't pass on Apple's new flagship laptop.

The main methods get an array of strings as an argument, these are the command line arguments you may pass to your program.Įvery array in java holds a variable called length that says how many elements are within that array.It's been almost a year since I've bought the MacBook Pro M1 ( arm64 processor) for my daily Java development as a freelance consultant.

To run it, we need to run java with the name of the class as the argument (Not the file!) Wrong java MyFirstClass.class This will create a file called MyFirstClass.class that holds the compiled java code.

If we take the code from the previous lesson and put it in a file called MyFirstClass.java, in order to compile it we need to run: javac MyFirstClass.java

In order for those to be available you must download and install JDK (Java Development Kit). You need to have a console and you need to have the following commands available in order to compile and run Java. It shouldn't really matter if you use Linux, Mac or Windows. This section is used for you to use Java at home and understand the basics of how things are done.Īfter creating a simple application that prints something to the screen, you need to compile your code and run it.
