![]() ![]() This is what I see on my machine: 1 % javac HelloWorld.java If you want to run the compiled version: 1 java HelloWorld Save the above as HelloWorld.java and compile it with: 1 javac HelloWorld.java Just to be sure that everything works, try to compile and run a simple program: 1 class HelloWorld Now, check if you’ve successfully installed the JDK with: 1 java -version 2 javac -versionĢ openjdk version "13" 3 OpenJDK Runtime Environment (build 13+33) 4 OpenJDK 64-Bit Server VM (build 13+33, mixed mode, sharing) 5 % javac -version Next step, is to move the extracted folder to a place where macOS searches for Java JDK: 1 sudo mv jdk-13.jdk /Library/Java/JavaVirtualMachines/ Extract the archive by double clicking on the file or, assuming it is in your Downloads folder, write this in your Terminal: 1 cd ~/Downloads 2 tar xf openjdk-13_osx-圆4_ Start by getting OpenJDK, chose the macOS version. If you prefer to use the Java version provided by the OpenJDK website, you will need to use Java 13. This is what I see on my machine: 1 % java -versionĢ openjdk version "11.0.4" 3 OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.4+11) 4 OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.4+11, mixed mode) 5 % javac -version From the AdoptOpenJDK page you will download a pkg file that you can install on your macOS machine directly by double clicking on it.Īfter you’ve installed the AdoptOpenJDK pkg file, check if you can use it with: 1 java -version 2 javac -version If you still need to use Java 11, use an alternative build like the one from AdoptOpenJDK. ![]() You can still get the archived version, but this is not recommended because it doesn’t include any new security patches. At this time, Java 11, the long term release or LTS, of Java is no longer supported on the OpenJDK website. If you would like to contribute or get involved in the project, please visit. Please join us in welcoming the OpenJDK community to GitHub. Now the OpenJDK projects can take advantage of some of the features we built for Java developers on GitHub including free code scanning to look for security vulnerabilities, notifications and remediation of known security fixes as well as semantic code navigation in GitHub (which is powered by the Java based Elasticsearch project). OpenJDK joins a number of our most popular projects here on GitHub all written in Java, including Gradle, Maven, jUnit5, Elasticsearch, Spring, Apache Spark, Selenium, Helidon and more. All of these integrations are now also open source and available in the OpenJDK GitHub organization. To do all this, the team created some fantastic integrations with the GitHub API as part of their Skara tooling. Some of the OpenJDK projects have also been busy adopting GitHub Actions for their CI builds. The team had to build custom CLI Tooling, bi-directional bridging with the OpenJDK mailing lists and integration with the OpenJDK bug tracking system. Like all big migrations, this was much more complex than just doing a hg-fast-export and then a git push. Previously, they were relying on self-hosted Mercurial servers this project involved bringing all of the development team and their tooling over to Git as well as moving the community to GitHub. The ‘Skara’ project has been an impressive effort from the entire OpenJDK community led by the Java Platform Group at Oracle. Therefore it’s a massive honor that we now get to help the team building the future of the Java language. The JDK project is at the heart of the Java community and Java is one of the most popular languages for projects on GitHub. The communities migration effort, codenamed Project ‘Skara’, brought JDK 16 main-line development into GitHub. Earlier this month we were thrilled to welcome the OpenJDK Community to GitHub.
