So it is always good to check the JAVA_HOME variable and ensure that it is set to a reasonable value, both for terminal execution and for effective use of Java development tools that may rely on it.I need to install java for a game i'm trying to use on the mac. look at JAVA_HOME or use the Maven toolchains plugin). export JAVA_HOME=`/usr/libexec/java_home -v 17`Īlso, some tools such as the openjfx maven plugin will not use the java version selected in Idea when executing a call to a JDK tool like jlink, but will instead have their own mechanism for finding a JDK to use (e.g. To select the version of the JDK to run in the terminal, configure the Java home setting as outlined in rzwitserloot's answer. This can sometimes mean that the app works when run in Idea, then fails when run in the terminal (or, at least that it is executed against a version of the JDK you didn't expect).
One common issue is that the version of the JDK registered for the project differs from the default version used in the terminal.

The JDKs installed by Idea will be located in the same location as outlined in Basil's answer for a manual install /Library/Java/JavaVirtualMachines/.

Use the Download JDK option to choose a vendor and version of the JDK that the IDE will automatically download, install and make available for selection.Use the Add JDK option to add a new JDK which you previously downloaded and installed using the method outlined in Basil's answer OR.Select a pre-existing JDK which has been registered with the IDE OR.Within IntelliJ, you can use the IDE to add new JDKs of selected versions from common vendors. This answer is specifically if you use Intellij on a Mac Use a JDK that includes the JavaFX/OpenJFX libraries.Īt least two vendors provide JDK installers that include the JavaFX/OpenJFX libraries:.Include the necessary OpenJFX libraries within your development project and within your final app, or ….JavaFXīe aware that for JavaFX, you have two options: Just use an installer for Java as you would for many Mac apps. But if new to Homebrew, skip it if your only goal is to install Java. If you already enjoy using the brew tool, proceed. No need for the Homebrew package manager. We are referring to the root Library folder that applies across all the user accounts on this Mac. We are not referring to /Users/your_user_name/Library/…. Note that this is not the Library folder within your home folder. In the Finder, choose Go > Go to Folder, and paste /Library/Java/JavaVirtualMachines/. Configure your IDE to use that new Java implementation you installed.Delete installer app that you downloaded.Verify installation by typing on a command-line in Terminal.app:.
