Making a cross-platform build of JavaFX using Gradle

Question

I'm working on a new project using Gradle and JavaFX. I have previously been able to create a cross-platform build using Maven, with the following pom dependencies:

<dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
            <version>13</version>
            <classifier>win</classifier>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
            <version>13</version>
            <classifier>linux</classifier>
        </dependency>
        <dependency>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
            <version>13</version>
            <classifier>mac</classifier>
        </dependency>

How do i go about doing something similar with Gradle? I have tried the following, with no success. Is the classifier syntax incorrect?

compile group: 'org.openjfx', name: 'javafx-graphics', version: '11.0.2:win'
compile group: 'org.openjfx', name: 'javafx-graphics', version: '11.0.2:linux'
compile group: 'org.openjfx', name: 'javafx-graphics', version: '11.0.2:mac'

Any hints would be greatly appreciated!

Answer 1

The solution turned out to be the following gradle build dependencies:

implementation group: 'org.openjfx', name: 'javafx-base', version: javaFxVersion, classifier: 'win'
implementation group: 'org.openjfx', name: 'javafx-base', version: javaFxVersion, classifier: 'mac'
implementation group: 'org.openjfx', name: 'javafx-base', version: javaFxVersion, classifier: 'linux'
implementation group: 'org.openjfx', name: 'javafx-controls', version: javaFxVersion, classifier: 'win'
implementation group: 'org.openjfx', name: 'javafx-controls', version: javaFxVersion, classifier: 'mac'
implementation group: 'org.openjfx', name: 'javafx-controls', version: javaFxVersion, classifier: 'linux'
implementation group: 'org.openjfx', name: 'javafx-fxml', version: javaFxVersion, classifier: 'win'
implementation group: 'org.openjfx', name: 'javafx-fxml', version: javaFxVersion, classifier: 'mac'
implementation group: 'org.openjfx', name: 'javafx-fxml', version: javaFxVersion, classifier: 'linux'
implementation group: 'org.openjfx', name: 'javafx-graphics', version: javaFxVersion, classifier: 'win'
implementation group: 'org.openjfx', name: 'javafx-graphics', version: javaFxVersion, classifier: 'mac'
implementation group: 'org.openjfx', name: 'javafx-graphics', version: javaFxVersion, classifier: 'linux'

This allows a javafx gradle build to be run on any OS.

Answer 2

The syntax is indeed incorrect in Gradle. Documentation will show you the different supported syntax.

The two most common are the map style you used and the : separated notation.

So taking one of your dependency as an example, you need to use either:

• compile group: 'org.openjfx', name: 'javafx-graphics', version: '11.0.2', classifier: 'win'
• compile 'org.openjfx:javafx-graphics:11.0.2:win'

Note that you should also stop using the compile configuration and instead use implementation. See this explanation to understand more on this topic.
