JavaFX (jfxmobile) with gradle-android-scala-plugin gives me "The 'java' plugin has been applied, but it is not compatible with the Android plugins."

[voxoid0]

I’m trying to build a Scala+JavaFX application for Android (the most awesomesterest cross-platform technology stack). I used the Gluon Eclipse plugin to create a “Basic Gluon Application”, then I followed the gradle-android-scala-plugin readme instructions.

When I run the androidInstall build task (from jfxmobile), I get the error "The 'java' plugin has been applied, but it is not compatible with the Android plugins." So apparently jfxmobile runs the java plugin; any ideas on how to make these two play nice?

My build script looks like this:

`

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.7'
        classpath "com.android.tools.build:gradle:1.3.1"
        classpath "jp.leafytree.gradle:gradle-android-scala-plugin:1.4"
    }
}

apply plugin: 'org.javafxports.jfxmobile'
//apply plugin: 'scala'
//apply plugin: 'eclipse'
apply plugin: "com.android.application"
apply plugin: "jp.leafytree.android-scala"

repositories {
    jcenter()
    mavenCentral()
    mavenLocal()
}


mainClassName = 'com.percebemusic.test.javafx.MainApplication'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
    }
}

// see https://github.com/saturday06/gradle-android-scala-plugin
android {
    compileSdkVersion "android-21"
    buildToolsVersion "22.0.1"

    defaultConfig {
        targetSdkVersion 22
        testInstrumentationRunner "com.android.test.runner.MultiDexTestRunner"
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }

    productFlavors {
        dev {
            minSdkVersion 21 // To reduce compilation time
        }

        prod {
            minSdkVersion 8
        }
    }

    sourceSets {
        main {
            scala {
                srcDir "path/to/main/scala" // default: "src/main/scala"
            }
        }

        androidTest {
            scala {
                srcDir "path/to/androidTest/scala" // default: "src/androidTest/scala"
            }
        }
    }
}

dependencies{
    compile 'org.slf4j:slf4j-api:1.7.5'
    compile "org.scala-lang:scala-library:2.11.7"
    compile "com.android.support:multidex:1.0.1"    
    testCompile "junit:junit:4.11"
    androidTestCompile "com.android.support:multidex-instrumentation:1.0.1", { exclude module: "multidex" }
}


tasks.withType(ScalaCompile) {
    scalaCompileOptions.deprecation = false
    scalaCompileOptions.additionalParameters = ["-feature"]
}

I take it no progress on this ? I'm just trying to build using com.android.application and scala plugins and am getting the same error.

I did eventually figure it out, though I don't remember the solution for this particular error, but perhaps the resulting overall guide would help you: http://joelbecker.net/blog/scala-javafx-on-android-ios-windows-osx
