Creating input.App in the process. This gradle-plugin is a convenient-wrapper for the javapackger, so you have to visit the official. No more using Apache Ant-calls, because this gradle-plugin wraps all calls and introduces workarounds and fixes for not-yet-fixed JDK-bugs. Using javafx-gradle-plugin enhances your build-script with javapackager -power.The basic package is a single folder on your hard drive that includes all application resources and the JRE. The Java packaging tools provide built-in support for several formats of self-contained application packages. Run it on a Windows machine, for OSX installers you will need to run it on a Mac, etc.7.1 Introduction.
![]() If you think that's just a strong case of NIH, feel free to grab what you want from me and send a patch to the other projects :) Just follow the GPL! Can I submit bundles created with jar2app to the Appstore?Jar2app may bundle your jar, but there are several steps you further need to take to submit your application to the Appstore. The solution I was left with was just rolling out my own. Most of the other alternatives require third-party tools that embed other functionality and which simply cannot be stripped. Packr uses a custom launcher and is meant to pack things for Mac OS X, Windows and Linux. Really, isn't it wonderful to have such an easy-to-use interface?If you're also considering why these contributions weren't just sent to one of the other projects, it is because this could not be done easily. Javafx Executable Wrapper How To Submit BundlesExamples: InstallJar2app relies on JavaAppLauncher (although you don't need to install anything). This will install the jar2app application/script and make it available for you to run. It will install to /usr/bin, but you can change this by passing your desired prefix to install.sh, as an argument. How do I install/uninstall it?Just clone the repository and run install.sh, or uninstall.sh to remove it. For more information on how to submit bundles to the appstore, see here and here. Additionally, if you so wish, your own JDK or JRE can be bundled and the Info.plist file will be updated to reflect this.I know that there are other solutions that write their own wrapper, but the provided wrapper seems to work great (it's also bundled by Weka). Essentially, all that jar2app has to do is create a directory structure (app files are just directories), pack JavaAppLauncher and your application in it and set appropriate values in an Info.plist file. The JVM can be bundled with the App file, or the system-wide-one can be used. This JRE/JDK should match the directory structure found in Oracle's JDK (i.e. It can be supplied as a folder or as a zipfile. You can, however, pass it a JRE/JDK with the -r, -runtime option. For a full list of options, see here Does jar2app bundle its own JRE/JDK? Can I bundle my own?By default, jar2app doesn't bundle any JRE or JDK, and the default will be used on each system. What exactly can I change?You can change many things, but more specifically, you can change the icon, the display name (the one that appears on the menu bar), the version and copyright information, the bundled JDK/JRE and the JVM options. Install cran package for macJar2app assigns values to the following keys: How does jar2app figure them out?There are several keys that Apple defines, and you might want to check them out. Apple defines several keys for its App format. You can change this behavior, and pass in another main class with the -m, -main-class option. It looks inside your jar file for the MANIFEST.MF file and extracts the name of the main class. Does jar2app figure the main class of my jar automatically? Can I change it?Yes it does. The default: com.jar2app.example. What you supplied ( -b, -bundle-identifier) CFBundleIdentifier: This is chosen from the following, in order: CFBundleIconFile: This is set to whichever icon you passed in, and ignored if no icon is used CFBundleExecutable: This is internally defined to JavaAppLauncher (from oracle) The name of the jar (excluding extension) The name of the app (passed as outputfile argument) What you supplied as bundle name ( -n, -name) What you supplied as display name ( -d, -display-name) NSHumanReadableCopyright: This is set to what you supply or the empty stringThe info.plist file will contain additional keys, but there are used to pass information to JavaAppLauncher (JVM arguments, JDK/JRE, etc) If I only pass the jar and no other options, what are the defaults used by jar2app?Jar2app assumes that you want to create an app file with the same basename as your jar file and in your current working directory. CFBundleSignature: This is chosen from what you supply or the string "?". CFBundleShortVersionString: This is chosen from the following, in order: What you supplied as short version ( -s, -short-version) What you supplied as version ( -v, -version) CFBundleVersion: This is chosen from the following, in order: App, as jar2app does it for you.Well, you should probably check this FAQ entry first. What you supplied as app name (it is the last unnamed argument, e.g. The app name is determined as so: How is the App name determined?You are probably also interested in this question and this question. The short version is that all names get set to the basename of your jar, and that versions are set to 1.0.0. The remaining options, such as the Icon, display name and others, are figured out as described in here. Have fun, report bugs and add features as you wish! Is there a GUI?This tool is so simple to use that it seems pointless to add a GUI. "It must be easy, right"? Turns out it wasn't so easy and most tools weren't straightforward, so, here's jar2app. To fix this, I decided to just package the jar in an app. This meant that whenever I wanted to launch applications bundled as jars (and that happens very often), I'd have to break my workflow and wait while spotlight figured itself out. You can change that by passing -l, -low-res-mode. It adds specific entries in the Info.plist file to ensure that retina screen is enabled by default. Does it work on retina screens?Yes it does. Use it with the default values for simple, easy and straightforward redistribution. Jar2app has many defaults that should not be used if you intend to distribute your application in very serious fashion. There are several parameters that you have to configure, including special unique keys and signatures. It's lacking mostly in JRE/JDK minimizing support, and it hasn't really been thoroughly tested when bundling things for the app store.If it's not your cup of tea, don't worry! There are other alternatives, such as the wonderful Packr, the official Oracle documentation, the official Apple documentation and the AppBundler project, part of which is used in jar2app. Are there other alternatives?Jar2app tries to do most of what the other tools do.
