You can also generate a local build which I’ll below. Notice I’m simplifying a bit, since you also need a certificate. Codename One makes that relatively simple with wizards etc. but that’s a bit of a big subject. The compilation process for iOS is very resource-heavy, as the plugin will compile the entire openJDK and other libraries twice to create a fat JAR that it will use to build your application.

Therefore, you should preemptively create a RAM disk to accommodate for the memory requirements. Notice that we created directories for embedded and desktop. We will produce a desktop build, because it takes no additional work to do so. However, we will not produce any builds for embedded devices. Second, run gradle init in the project’s root directory to initialize the gradle repository.

GWT is a breakthrough technology from Google that allows development of the entire application in pure Java. The user interface is built using Swing-like components and simple layouts, and then it is compiled into a JavaScript executable file that is embedded in HTML page. During the construction the developer only deals with Java, and there is simulated mode that allows testing without doing the full compilation. GWT implements most of the core Java APIs and there is a fairly straightforward way of invoking Java services from the user interface. GWT takes care of browser compatibility and optimizations by producing different compiled versions of the application for different browsers. Using GWT is a good solution, but it still force you to rebuild some parts, design new UI, retest it, get new bugs with it, fix them in several iterations etc.
