You should get a response showing the same version as the java version you just installed. You will see a command not found message or something similar if it is not installed.

You could proceed with the new install if there is a more recent version and you wish to upgrade. If there is another version, you may want to take note of the version. There’s a chance it could have already been installed by another application. Before starting the installation, I first recommend checking to see if you already have a version of Java on your Mac.

With the symlink in place, IntelliJ detects the installation as expected. $ sudo ln -s /Library/Java/JavaVirtualMachines This was a very easy fix to put in place. Selecting the Project SDK dropdown did not give me the option to use the JDK I just installed.Īfter digging around a bit, I discovered that this is because brew may not symlink the JDK installation to /Library/Java/JavaVirtualMachines.
