Search this website for something like “Mac Java quit preferences” to find examples of how that works.

#JAVA APPLICATIONS FOR MAC CODE#

If you want to build a Mac/Java application whose menu items work like native macOS applications, you’ll have to code that into your application. I use Proguard for this purpose, and you can search this website for something like “Mac Java Proguard” to find those examples.

If you want to build a Mac application that uses several Jar files, you’ll need a slightly more-complicated process. This build process uses the Sun/Oracle AppBundler Jar file, which is documented here. In case that URL ever goes away, I also included those value names in the file in this project named LSApplicationCategoryType.txt.

See this url for more information on the possible values. This variable is used to set the LSApplicationCategoryType key in the ist file in your application. If you’re going to build an application that you want to distribute to other users - such as through the Apple/Mac store - you’ll want to be sure to set the app_category variable in the build.xml file properly. Note 2: Setting the “application category” That script adds the NSHighResolutionCapable key to the application’s ist file. If you look at that script you’ll see that it (a) runs ant, then (b) runs the _addHiResKeyToPlistFile.sh script. Run the script named _build.sh to build your application.Set the APP_NAME variable in that file to the same app_name you use in the build.xml file.Edit the _addHiResKeyToPlistFile.sh file.To get a smooth font with your application, follow this build process: This is usually immediately apparent in the title bar of your application. Java applications built like this seem to have non-smooth fonts on macOS. (I assume your application is a Java Swing or JavaFX GUI app.) You can then type type open release to open the folder that contains your app, and then you can use the Mac Finder to copy your app to your desktop (or anywhere else). If all goes well, your application will be shown in a few moments. Assuming you named your application “HelloWorld”, type open release/HelloWorld.app to run your application.

In the macOS Terminal (or similar app), type ant to build the application.Eventually you’ll want to create your own icon file as a macOS icns file, but you can start with my world.icns file until you create your own.Change the variables at the top of the build.xml file to match your application.Copy your Jar file into the current directory.If you have that, this build process should work if you don’t have that, you’ll need a more-complicated build process. (I didn’t test it without one.)Īs mentioned earlier, the biggest assumption is that your application completely exists in one Jar file such that you can run it with the java -jar command. The application probably needs a META-INF/MANIFEST.MF file in that Jar file.This distribution includes a hello.jar file to show how things work. Your Java application needs to be in one Jar file.I tested this with Ant 1.10.1, which I installed with Homebrew. I tested this with Java 1.8 on macOS 10.12.5. The requirements for building a macOS/Java application with this specific build process are:

#JAVA APPLICATIONS FOR MAC HOW TO#

I write about it in my How to use javapackager to build a macOS application bundle tutorial.

Update: While you can still use the AppBundler described in this article - and in some ways it’s a more obvious approach to building a Mac/Java application - Oracle now recommends building Mac/Java applications with their javapackager tool. They created an “AppBundler” Jar file that can be used with Ant to build a Mac application, and that’s what I use in this process.

#JAVA APPLICATIONS FOR MAC SERIES#

Many years ago, Sun (now Oracle) created a process by which you could create a Mac application from a Java Jar file (or even a series of Jar files). The directory must end with the extension, “. If you don’t already know it, a macOS application is actually a directory that contains a series of files in a specific, well-defined layout. More on those later.)Īs those assumptions infer, you won’t have a “perfect” app whose menu items work exactly like a native Mac application, but you will at least have a Mac application that you can start by double-clicking an application icon. (I understand that those first two items can be big assumptions.

  • I assume your application is a Java Swing or JavaFX GUI app.
  • You aren’t concerned about implementing macOS-specific features, like enabling the Preferences and Quit menu items, or implementing Mac-specific keystrokes in your app.
  • You have a single Jar file you can already run with the java -jar command.
  • I tested this with Java 1.8 on macOS 10.12.5 (Sierra) on June 29, 2017. In this article I’ll show how to build a macOS application from a Java Jar file.
