javafx - HelloWorld with JavaFXPorts and gradle on Android

itemprop="text">

so I'll try to build a
mobile application with Gluon and JavaFX.

So, i
follow this step.

1. Install
   ADT and add ANDROID_HOME to my enviroment (OS
   Mac)


2. Install SceneBuilder from official
   site


3. Install last eclipse version
   (neon)


4. generate a FXML file from
   ScendeBuilder



5. With eclipse wizard, i generate
   a SingleViewGluon project


6. import FXML on my eclipse
   project and use in my JavaFX
   application

Now I try to
generate apk from console, I'm in the root of project and
launch

./gradlew clean
            build

and that's ok,
after

./gradlew
            android

and i get
that's error

FAILURE: Build failed with an exception.

• What went wrong: Failed to capture
  snapshot of input files for task 'mergeClassesIntoJar' during up-to-date
  check.
  java.io.FileNotFoundException:
  /Users/franksisca/Library/Android/sdk/extras/android/support/multidex/library/libs/android-support-multidex.jar
  
  (No such file or directory)




• Try: Run
  with --stacktrace option to get the stack trace. Run with --info or --debug option to
  get more log output.

BUILD
FAILED

How i solve
this? Someone has a step-by-step tutorial to build a mobile application with
JavaFXPorts?

thanks in
advance

Answer

It seems android-support-multidex.jar which
is necessary for the task 'mergeClassesIntoJar' is not
Found. So Go to Sdk Manager.exe, which is located in the root of
ANDROID_HOME, and update all the repositories. And run the
gradle clean build.

This should probably
Work.
