Why is "Duplicate zip entry [classes.jar: android / support / v7 / appcompat / R $ styleable.class]" using android-sdk-plugin?

I am using pfn / android-sdk-plugin in a project with the following build.sbt

:

import android.Keys._

android.Plugin.androidBuild

platformTarget in Android := "android-19"

name := "LDApp"

organization := "com.myapps.app.android.ldapp"

version := "1.0"

scalaVersion := "2.10.4"

useProguard in Android := true

libraryDependencies ++= Seq (
  "com.myapps.libraries.android" %% "androidlibs" % "0.1-SNAPSHOT"
)

proguardCache in Android ++= Seq (
  ProguardCache("androidlibs") % "com.myapps.libraries.android" %% "androidlibs",
  ProguardCache("appcompat-v7") % "com.android.support" % "appcompat-v7"
)

      

        
        
        
      

    

Whenever I try sbt android:run

, I get an error like Duplicate entry

, appcompact-v7 is included myapps.libraries.android

, so I haven't explicitly included in this application. Below is the error log

R$styleable.class

was also generated as part of the application and is also part of the compact-v7 library, how to fix this issue, although similar issues around these solutions did not help.
