Your first Java program has run successfully. Here we are just printing a string passing it to the API System. We will cover all the concepts in the code, but you are welcome to take a closer look!

Skip to content Home. Search for:. Jdk 1. Its a self extracting executable file which will install Java in your system! Before diving directly into building OpenJFX, lets get our feet wet by learning what kinds of things we can call from the command line, and how to get help when we need it.
The first command you should execute is tasks :. The tasks task is extremely helpful. You use it to discover all the other things you can do with this build file. You notice at the top of the output the phrase 'All tasks runnable from root project'. The 'root' project is 'rt'. That is, we are in the root project. Below the root project are a series of sub projects, some of which are referred to as modules or 'components'. But more about those later. Gradle then tells us what the default tasks are.
In this case, our default task is the 'sdk' task. This is the task that will be executed if you just call 'gradle' alone without providing any additional arguments. After this comes a listing of different tasks, broken out by group. The first group is the 'Basic' group which contains the tasks you may find yourself using most often. These are all named and have a description provided. For example, if I wanted to execute the 'clean' task, then I would do so like this:.
Finally, the tasks task gives us a useful hint that we can pass the --all argument in order to see all of the tasks in more detail. This produces a lot more output, but really gives an in depth look at what tasks are available for you to call. I mentioned above that our root project is called 'rt', and that we have sub-projects in the gradle build. To see all of the projects available to you, execute the projects task which you will notice was in the 'Help tasks' group produced by the tasks task.
This lists not just what projects are available, but what their name is, and what the project hierarchy is. Projects in gradle are named according to their depth. So the root project is simply named 'rt' or whatever your top directory is named.
The immediate subprojects are all prefixed with a ':'. Sub-subprojects have their parents in their name, for example, ':graphics:effects-jsl'. When you execute a command such as gradle assemble what actually happens is that Gradle locates the assemble task on all projects and executes them.
TODO Is this entirely accurate? There are a couple other tricks-of-the-trade that you should be aware of. You can execute any gradle command with --info or --debug in order to get more output. Running in --info mode provides some additional debugging output that is very useful when things go wrong.
One more trick is the --profile argument. You can perform any gradle task and use the --profile argument. The report breaks down how much time was spent in configuration, dependency resolution, and task execution. It further breaks it down by project. This gives useful metrics for tracking down which parts of the build take the longest and hopefully tighten up the build times.
There are three main things you may want to do on a regular basis when working on JavaFX: building, testing, and creating documentation. Lets look at each of these in turn. The simplest basic task to build is the sdk task. The sdk task will compile all Java sources and all native sources for your target platform. It is the default task which is executed if you do not supply a specific task to run.
It will create the appropriate sdk directory and populate it with the native dynamic libraries and the jfxrt. Because the SDK is not distributed with documentation, the javadocs are not created as part of the sdk task by default. Once the sdk task has completed, you will have and SDK distribution which you could run against or give to somebody else to run. Gradle automatically handles the downloading of all dependencies such as Antlr and SWT located under rtbuildlibs. The build is configured to support cross builds , that is, the ability to build an SDK for a platform other than the one you are building from.

The build is configured to support cross builds , that is, the ability to build an SDK for a platform other than the one you are building from. There are multiple gradle files located in buildSrc which represent specific compile targets. These include:. Each of these have specific prerequisites that must be met before they can be built.
ARM soft float and hard float can be cross built from Linux. This is a comma separated list. Assuming you have already setup the prerequisites for building ARM for example, when targeting the Raspberry PI , you would invoke gradle like this:. The build can be customized fairly extensively through the use of Gradle properties.
