Error after running the default Gluon project (: dex FAILED)

Question

I downloaded the Gluon plugin for Netbeans to deploy JavaFX application to Android. It ran successfully on the desktop but when I execute the android task, it throws an error:

Executing: gradle :android

:compileJava UP-TO-DATE
:compileRetrolambdaMain UP-TO-DATE

:dex FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':dex'.
> org.gradle.api.GradleException (no error message)

* Try:

BUILD FAILED

Total time: 4 mins 29.297 secs

Here's my software configuration:

• I used JDK8u45 (I also set the path for JAVA_HOME)
• I used Netbeans 8.0.2 for the IDE
• I downloaded the Android SDK with API21 in it (I also set the path for ANDROID_HOME)
• I downloaded Gradle2.4 (I also set the path for GRADLE_HOME)
• I used Windows XP for the OS (32 bit)

What could be the cause of that error?

Here's the build.gradle:

 buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b9'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
}

mainClassName = 'com.gluon.GlounMainApp'

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

Here's the stacktrace:

Answer 1

I had the same problem now it's solved .Now I am able to compile and make my android apk .

So these are the steps I followed

1. Make sure you have updated your sdk manager -> support library to latest version (23.1.1) it was the latest for me when I posted this answer. This will update

H:\sdk\extras\android\support\multidex files

2. Make sure you add your android sdk location in build.gradle androidSdk='H:/ADT BUNDLE/sdk'

like this

buildscript {
    repositories {
        jcenter()
    }
    dependencies {

           classpath 'org.javafxports:jfxmobile-plugin:1.0.0-b9'


    }
}

apply plugin: 'org.javafxports.jfxmobile'


repositories {
    jcenter()
}

mainClassName = 'com.fff.Fff'

jfxmobile {
    android {
        manifest = 'src/android/AndroidManifest.xml'
        androidSdk='H:/ADT BUNDLE/sdk'

    }
}

If you are working in a 32 bit PC

Set environment variable name JAVA_OPTIONS with value Xmx1024M

If you are working in a 64 bit PC

make sure you install JDK that is 64 bit and not 32 bit JDK
