On macOS, it is recommended to use SDKMAN to manage and install OpenJDK.

1. Install SDKMAN:

   $ curl -s "https://get.sdkman.io" | bash
   $ source "$HOME/.sdkman/bin/sdkman-init.sh"

2. Install and manage Java versions:

   • List available/installed JDKs: sdk list java
   • Install a specific version (e.g., Zulu JDK 8): sdk install java 8.0.292-zulu
   • Set a version globally: sdk default java 8.0.292-zulu
   • Set a version for the current shell only: sdk use java 8.0.292-zulu
   • Check current version: sdk current java
   • Check JAVA_HOME path: echo $JAVA_HOME

$ curl -s "https://get.sdkman.io" | bash
$ source "$HOME/.sdkman/bin/sdkman-init.sh"

$ sdk list java
$ sdk install java 8.0.292-zulu
$ sdk default java 8.0.292-zulu
$ sdk use java 8.0.292-zulu
$ sdk current java
$ echo $JAVA_HOME

To set up the Java Development Kit (JDK 8) on Windows, download the OpenJDK build from the following link:

If you are using Eclipse on Mac and need to manually point to your JDK installed via SDKMAN, modify your eclipse.ini file. Add the -vm flag followed by the path to your JDK's bin directory.

Example configuration snippet for eclipse.ini:

-vm
