Answer 1

Try replacing:

javaRuntime = 'C:\\Program Files\\Java\\jdk1.7.0_45'

with:

javaRuntime = 'C:/Program Files/Java/jdk1.7.0_45'

Answer 2

Actually, loading a resource with Gradle might be different from using your IDE resource system.

It is better to use the ClassLoader :

URL myFxmlURL = ClassLoader.getSystemResource("fxml_example.fxml");
FXMLLoader loader = new FXMLLoader(sampleUrl);

Parent root = loader.load(myFxmlURL);

Answer 3

I'm really late to the party...but the accepted didn't work. I (randomly) added 'javafx.fxml' to the list of modules, like this

javafx {
    version = "14"
    modules = [ 'javafx.controls', 'javafx.fxml']
}

...and it solved the issue.

Answer 4

Your FXML files are probably not packaged into your jar.

Try adding this to your build.gradle file:

sourceSets {
  main {
    resources {
        srcDirs = ["src/main/java"]
        includes = ["**/*.fxml"]
    }
  }
}
