I just wanted to say that, while the Azul JDK works natively on Apple M1 and its speed is great, there are still issues. | | 18.ea.3 | open | | 18.ea.3-openĬhoose one and install it using the command sdk install java IDENTIFIER, i.e.: Vendor | Use | Version | Dist | Status | IdentifierĪzul Zulu | | 16.0.1 | zulu | | 16.0.1-zuluīellSoft | | 16.0.1 | librca | | 16.0.1-librca Set sdkman_rosetta2_compatible=false (see sdkman config)Īfter that, you will see a list of compatible with M1 JDKs: sdk list java You can install the Java JDK using sdkman (see sdkman install): vim. Note that Microsoft's been working on the OpenJDK branch of AArch64 (for ARM-based Windows 10) for a while, which goes back to: A lot of the hard work was already done. Microsoft's (yes, really) GitHub source repo for an early access OpenJDK16 build for macOS on AArch64.Donate to the effort or contribute a pull request if you want it to go faster. You didn't pay them, you have no contract, and they don't owe it to you. My assumption is that the ARM branch of the OpenJDK source code the macOS bits that already exist for the macOS 圆4 release can be combined rather easily once someone with some familiarity with the OpenJDK source code has an M1-based macOS system to test it on, which should mean an adoptopenjdk macos-aarch64 release should be here within the month.īut, open source. But, it's an open source effort, so if you're anxious, by all means, read up and contribute :)Īpple has not given any details on this architecture whatsoever until November 10th 2020, unless you bought a development kit box for it (a Mac Mini with an A14 chip, which isn't an M1 chip, but close enough I guess), and signed a big NDA.Īs a rule, open source projects will run as fast as possible in the opposite direction if you wave an NDA around, so if you dislike this state of affairs, I don't think it's wise to complain to adoptopenjdk or other packagers and open source projects about it :)įortunately, now it's out, and an NDA is no longer required. That is to say: It should not be a herculean effort to create an adoptopenjdk release that runs on M1s natively, so presumably, it will happen. So: It's not there yet, but note that JDKs for ARM have been available for more than decade, and whilst JDK 15 has dropped support for a bunch of exotic OS/architecture combinations (such as Solaris), ARM development has always remained at least partially relevant (even if so far it's mostly an Oracle commercial license offering). That (probably) won't run on macOS on M1 hardware, but that's 95% of the work already done. If you instead leave Operation System on 'any', you'll note aarch64 is in there, and this gets you to a Linux release for ARM processors. Possibly, as Apple no doubt has a bunch of extensions built into their M1 designs, and Apple gets its own. So when you want to change the JDK you change only the JAVA_HOME variable and leave PATH as it is.On this page: AdoptOpenJDK Latest Releases you can select 'macOS' from the 'Operating System' dropdown, and then from 'Architecture', it's currently only 圆4, but soonish there should be AArch64 or ARM64 (those are usually the shortcodes for 64-bit ARM). Note: You can also point JAVA_HOME to the folder of your JDK installations and then set the PATH variable to %JAVA_HOME%\bin. If you want to uninstall - just undo the above steps. To see if it worked, open up the Command Prompt and type java -version and see if it prints your newly installed JDK. Enter the variable value as the installation path of the JDK (without the bin sub-folder).The following is a typical value for the PATH variable: C:\WINDOWS\system32 C:\WINDOWS "C:\Program Files\Java\jdk-11\bin".Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.Click Advanced and then Environment Variables.You may need Administrator privileges to extract the zip file to this location. C:\Program Files\Java\ and it will create a jdk-11 folder (where the bin folder is a direct sub-folder).
