Hi Diego, I have downloaded the sources and imported the project with the "Import project from external model" -> Gradle.
I am able to build it in intellij from the gradle tab (openjdk-jfx -> Tasks -> build -> build). I have used Sdkman to install gradle 5.3.1 and ant. I have used Ubuntu 19.04 beta and IntelliJ Idea 2019.1 Ultimate. Cheers.
