Can't access local storage service - gluon-mobile

Question

Similar question but didn't help: JavaFXPorts(Gluon Plugin) Saving Files on Android
I want to access the local storage on desktop and mobile. For now I'm testing on desktop. Whenever i launch the program I get the following in the error stream:
Mar 18, 2017 3:57:47 PM com.gluonhq.charm.down.Platform <clinit>
SEVERE: javafx.platform is not defined. Desktop will be assumed by default.

The trimmed down gradle build file is
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'org.javafxports:jfxmobile-plugin:1.3.2'
}
}
apply plugin: 'org.javafxports.jfxmobile'
apply plugin: 'eclipse'
jfxmobile {
downConfig {
version = '3.0.0'
plugins 'display', 'lifecycle', 'statusbar', 'storage' // <-- storage included by default
}
android {
compileSdkVersion = 23
manifest = 'src/android/AndroidManifest.xml'
}
ios {
infoPList = file('src/ios/Default-Info.plist')
forceLinkClasses = [
'com.gluonhq.**.*',
'javax.annotations.**.*',
'javax.inject.**.*',
'javax.json.**.*',
'org.glassfish.json.**.*'
]
}
}
eclipse {
classpath {
downloadJavadoc = true
downloadSources = true
}
}
repositories {
jcenter()
maven {
url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
}
}
mainClassName = 'com.foo.MainClass'
dependencies {
compile 'com.gluonhq:charm:4.3.1'
}
task wrapper(type: Wrapper) {
gradleVersion = '3.4'
}
Not sure what this version is
jfxmobile {
downConfig {
version = '3.0.0'
because if I change it to 4.3.1 Gradle gives me an error (can post if relevant).
Also I tried adding to dependencies {
desktopRuntime "com.gluonhq:charm-down-desktop:4.3.1"
like in the linked question but it did nothing.
