delete the %USER%/.android and %USER%/.gradle and delete every thing related to android studio and reinstalled it
use a VPN ( tried 3 )
but unfortunatly, nothing helped me
for further info: I am building fluxstore app

I still think its a connection issue . is maven google available in your browser with no VPN ?
if no then here is a old solution of mine , on how to configure gradle to use you VPN properly . Because you need to tell gradle to send request over VPN using gradle.properties file .

Have you tried restarting android studio? or have you try cleaning / re-build the project? And pls also try to go to file -> invalidate caches / restart and then press that and press invalidate caches and restart.

I just found that there are bugs like this in Android Studio 3.1, pls try follow this link

DuplicateFileException in apk build using Kotlin

I am trying to build a basic app using Kotlin/Anko but I am getting the following duplicate file exception
Execution failed for task
':app:transformResourcesWithMergeJavaResForDebug'.>

Following is the code for the app level gradle file:

// in the individual module build.gradle files
}
}
allprojects {

}
task clean(type: Delete) {

And this is the basic code for the MainUI file
class MainUI : AnkoComponent<MainActivityKotlin> {
override fun createView(ui: AnkoContext<MainActivityKotlin>): View = with(ui) {
coordinatorLayout {
verticalLayout {
// maybe put some content here
}
floatingActionButton {
imageResource = android.R.drawable.ic_menu_edit
onClick {
ui.owner.startActivityForResult<MainActivityKotlin>(1)
}
}.lparams {
gravity = Gravity.BOTTOM or Gravity.END
}
}
}
}
And the content is set on MainActivityKotlin file using the method MainUI().setContentView(this) in its onCreatemethod.
I have tried deleting the gradle cache and building the project again but nothing works. Please let me know where am I going wrong?

Remove compile "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version" from your gradle
Remove also all buildscript section from you app level gradle

Try this one:
compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
compile ("org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version") {
transitive = false
}
Also you don't need the android-extensions dependency anymore, as it's bundled into the plugin. Just having the apply plugin: 'kotlin-android-extensions' in your gradle is enough.

You are adding the same class with different versions twice.
You are using the Google play services modules with different releases:
Use:
compile 'com.google.android.gms:play-services-maps:8.4.0'
compile 'com.google.android.gms:play-services-location:8.4.0'
