How do you add a "system" dependency in Gradle?

Question

I have a pom.xml that looks like this:

<dependencies>
    <dependency>
        <groupId>javafx-packager</groupId>
        <artifactId>javafx-packager</artifactId>
        <version>1.8.0_40</version>
        <scope>system</scope>
        <systemPath>${java.home}/../lib/ant-javafx.jar</systemPath>
    </dependency>
</dependencies>

How do I do the same in Gradle?

Update: I tried doing this:

dependencies {
    compile files("${System.getenv('JAVA_HOME')}/../lib/ant-javafx.jar")
}

as suggested by Giuseppe Ricupero, but I'm still getting the compile errors:

>gradle build

The full pom.xml I'm trying to convert to Gradle is:

        </dependency>
    </dependencies>
</project>

Update 2: I tried gradle init like Giuseppe Ricupero recommended and it came up with this build.gradle:

apply plugin: 'java'
apply plugin: 'maven'

group = 'de.dynamicfiles.projects.javafx.bundler'
version = '1.0.1-SNAPSHOT'

description = """"""

sourceCompatibility = 1.8
targetCompatibility = 1.8
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

repositories {
    maven { url "http://repo.maven.apache.org/maven2" }
}

dependencies {
    system group: 'javafx-packager', name: 'javafx-packager', version: '1.8.0_40'
}

but that doesn't work, it throws this error:

> Could not find method system() for arguments [{group=javafx-packager, name=javafx-packager, version=1.8.0_40}] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

UPDATE

The gradle init task automatically (try to?) convert(s) the pom.xml into the equivalent gradle files. You can try them:

build.gradle

apply plugin: 'java'
apply plugin: 'maven'

group = 'de.dynamicfiles.projects.javafx.bundler'
version = '1.0.1-SNAPSHOT'

description = ""

sourceCompatibility = 1.8
targetCompatibility = 1.8
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

repositories {
    maven { url "http://repo.maven.apache.org/maven2" }
}

dependencies {
    system group: 'javafx-packager', name: 'javafx-packager', version:'1.8.0_40'
}

settings.gradle

rootProject.name = 'custom-file-extension-windows-bundler'

If you mix this with the original answer:

apply plugin: 'java'
apply plugin: 'maven'

group = 'de.dynamicfiles.projects.javafx.bundler'
version = '1.0.1-SNAPSHOT'

description = """"""

sourceCompatibility = 1.8
targetCompatibility = 1.8
tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

repositories {
    maven { url "http://repo.maven.apache.org/maven2" }
}

dependencies {
    compile files("${System.getenv('JAVA_HOME')}/lib/ant-javafx.jar")
}

it works.

Original answer

I think you need just to add a file dep like:

dependencies {
    compile files("${System.getenv('JAVA_HOME')}/../lib/ant-javafx.jar")
}

You can see more in the docs.
