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 Get started with v4.1.4 12K+ stars Migrate from Vert.x 3. Eclipse Vert.x Reactive applications on the JVM. Classes from J2SE-1.4 if available.
Bundle For Osx Using Eclipse Java Series Of FilesThe directory must end with the extension, “. BackgroundIf 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.)As 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.You’ll need the Java SDK installed. RequirementsThe requirements for building a macOS/Java application with this specific build process are: I write about it in my How to use javapackager to build a macOS application bundle tutorial. 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.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.This distribution includes a hello.jar file to show how things work. Your Java application needs to be in one Jar file. (You may get an error if it isn’t set.) Make sure JAVA_HOME is set. I tested this with Ant 1.10.1, which I installed with Homebrew.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.)As 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. 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. Unfortunately certificate installer has stopped androidThe Mac/Java AppBundlerThis 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. This variable is used to set the LSApplicationCategoryType key in the Info.plist file in your application.See this apple.com url for more information on the possible values. That script adds the NSHighResolutionCapable key to the application’s Info.plist file.Note 2: Setting the “application category”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. 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. SummaryIn summary, if you wanted a simple way to convert a Java Jar file into a macOS application, I hope this process is helpful. Search this website for something like “Mac Java quit preferences” to find examples of how that works. 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/Java application whose menu items work like native macOS applications, you’ll have to code that into your application.
