buildscript {
    ext.kotlin_version = '1.1.60'
    ext.tornadofx_version = '1.7.8'
    repositories {
        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.3'
        classpath 'no.tornado:fxlauncher-gradle-plugin:1.0.16'
    }
}
apply plugin: 'kotlin'
apply plugin: 'application'
apply plugin: 'com.github.johnrengelman.shadow'
apply plugin: 'no.tornado.fxlauncher'

repositories {
    mavenLocal()
    mavenCentral()
}
dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    compile "no.tornado:tornadofx:$tornadofx_version"
    compile 'org.controlsfx:controlsfx:8.40.12'
    compile "org.apache.commons:commons-dbcp2:2.1.1"
    compile 'com.google.guava:guava:23.5-jre'
}

Try looking up docs on each dependecy (or in sample code..) to see if youre using the right repositories (where the libs a retrieved from), theres more repos out there than mavenCentral... and the buildscript ones dont help for the app ones...
