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.
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.
Gradle provides many ways to supply properties to the build system. However the most common approach will be to use a gradle.
Simply make a copy of gradle. The gradle. Almost all other properties are derived automatically from this one. Typically, then, the version of Java you will be using to compile with will be the version of Java you have setup on your path. The next basic task which you may want to perform is test. The test task will execute the unit tests.
You generally will execute the top level test because unlike with Ant, Gradle will only re-execute those tests which have changed or were dependent on code that was changed on subsequent runs. You can of course execute gradle cleanTest in order to clean all the test results so they will run fresh. Or, if you want to execute only those tests related to a single project, you can do so in the normal fashion:.
Gradle gives helpful output during execution of the number of tests completed and the number skipped without dumping out lots of output to the console unless you opt for --info. For the sake of performance, most of the tests are configured to run in the same VM.
However some tests by design cannot be run in the same VM, and others cannot yet run in the same VM due to bugs or issues in the test. In order to improve the quality of the project we need to run as many tests as possible in the same VM. The more tests we can run on pre-integration the less likely we are to see failures leak into master. Being able to run 20, tests in a minute is extremely useful, but not possible, unless they run in the same VM. Something to keep in mind.
Using the results of a modular OpenJFX build is quite simple. A 'run' args file can be used to point to the overriding modules that are in your build. The run.
A script is provided that will recreate the xpatch. The following can be used to set up an alias that can be used to launch a JFX application, but using the FX binaries from your development tree. This alias will override the modules built into JDK9. In Windows, the paths for the alias can be a bit tricky to get right, as the JDK wants native Windows paths, and cygwin often works better with a Unix path.
Here is an example that works with Cygwin:. See the following instructions for building OpenJDK. During the build process, we generate some files for use by the build, and also by developers working in the sandbox. Each of these files has a 'test' variant, for example 'testrun. These files are altered to add in the 'shims' version of the module. Use the 'copyGeneratedShims' or 'test' task. When dealing primarily with unit tests, additional arguments are needed to access non public API from within the unit tests.
These additional arguments have been placed in 'addExports' that are local to the tests that need them. Care should be taken when modifying these files, as additions may mean that package module-info may need updates too. If you are trying to fix access by another module, it likely is the wrong place. Adding a new package or changing package visibility will be a multi step task that will require at least two change sets to implement.
Our developer sandbox build uses several items to work around module export during build and testing that you should be familiar with. Be sure to link this new followup JBS to the one you started with. Modify affected modules module-info to reflect the proposed changes. These changes will only directly affect the current build java compile process. It is key to remember that the java runtime will ignore any changes to module-info, even while it uses '--patch-module'. Mark any additions with a comment containing the 'Completion JBS' number, like this:.
Complete development of your new package and adding unit test coverage, and all of the other process we normally do. Your complete change set will now contain all of the delta required for the nightly build and test your changes.
The promotion process will soon merge your module-info changes into the JDK. Once there is a promoted JDK that has the new module-info changes, it is possible to move to the second step. One consideration - building a local development copy of the JDK is not difficult. In some cases, it may be useful to create a local developer JDK that incorporates the module-info changes, even before development of the changeset it complete.
