A macOS application is actually a directory that contains a series of files in a specific, well-defined layout, ending with the extension ".app ".
Sun (now Oracle) created a process by which you can create a Mac application from a Java Jar file using an "AppBundler" Jar file that can be used with Ant.
Oracle now recommends building Mac/Java applications with their javapackager tool, which is a more preferred approach compared to the AppBundler.
Requirements for building a macOS/Java application include Java SDK installed, Ant installed (e.g., with Homebrew), and setting JAVA_HOME.
