In this article, I will demonstrate how to install Java OpenJDK 14 on macOS Catalina in 2020.
Download and Install OpenJDK 14
.tar.gz version of OpenJDK 14 from jdk.java.net/14/.
sudo mv openjdk-14.0.1_osx-x64_bin.tar.gz /Library/Java/JavaVirtualMachines/ cd /Library/Java/JavaVirtualMachines/ sudo tar -xzf openjdk-14.0.1_osx-x64_bin.tar.gz sudo rm openjdk-14.0.1_osx-x64_bin.tar.gz
Next, execute the following command to find out where JDK 14 is located:
$ /usr/libexec/java_home -v14 /Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home
and append the resulting path as an export into your
echo -n "\nexport JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-14.0.1.jdk/Contents/Home" >> ~/.bash_profile
and make sure to apply the changes:
You should now be able to run java:
Depending on your security settings, the following warning needs to be accepted by clicking “Open”:
You should then see an output similar to the following:
openjdk version "14.0.1" 2020-04-14 OpenJDK Runtime Environment (build 14.0.1+7) OpenJDK 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)
Congratulations! You have installed OpenJDK 14.
