In this article, I will demonstrate how to install Java OpenJDK 15 on macOS Big Sur in 2020.
Download and Install OpenJDK 15
Download the .tar.gz
version of OpenJDK 15 from jdk.java.net/15/ and move the file to /Library/Java/JavaVirtualMachines/ on your mac. Then, extract it and delete the archive:
sudo mv openjdk-15.0.1_osx-x64_bin.tar.gz /Library/Java/JavaVirtualMachines/ cd /Library/Java/JavaVirtualMachines/ sudo tar -xzf openjdk-15.0.1_osx-x64_bin.tar.gz sudo rm openjdk-15.0.1_osx-x64_bin.tar.gz
Next, execute the following command to find out where JDK 15 is located:
$ /usr/libexec/java_home -v15 /Library/Java/JavaVirtualMachines/jdk-15.0.1.jdk/Contents/Home
and append the resulting path as an export into your .bash_profile
(or, change the existing JAVA_HOME
entry in your .bash_profile
if it already exists):
echo -n "\nexport JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk-15.0.1.jdk/Contents/Home" >> ~/.bash_profile
and make sure to apply the changes:
source ~/.bash_profile
Test Java
You should now be able to run java:
java -version
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 "15.0.1" 2020-10-20 OpenJDK Runtime Environment (build 15.0.1+9-18) OpenJDK 64-Bit Server VM (build 15.0.1+9-18, mixed mode, sharing)
Congratulations! You have installed OpenJDK 15.
