Basic Gluon Mobile plugin project for InteliJ IDEA fails to run from IDE

Question

I am trying to run a basic Gluon Mobile application in the InteliJ IDEA IDE. I believe I have all the required dependencies installed. When I create a new Gluon Mobile Single View project and try to run the destop application without changing any code I get the following error.

> Task :TESTApp:run FAILED

I've looked around online and I haven't come up with an idea of what to try. The build task seems to be fine here is the output of that:

The IDE creates two build.gradle files, one in the top level directory and one in the source directory. The top level file has only one line: apply plugin: 'base' The build file in the src directory is more interesting:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.17'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
    maven {
        url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
    }
}

mainClassName = 'com.tenman.TESTApp'

dependencies {
    compile 'com.gluonhq:charm:5.0.2'
}

jfxmobile {
    downConfig {
        version = '3.8.6'
        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'display', 'lifecycle', 'statusbar', 'storage'
    }
}

Thank you for any thoughts or ideas on what to try.
