两次指定相同的输入jar [\ .. \ Android \ sdk \ platforms \ android-26 \ android.jar]

Question

当我尝试从Android Studio创建构建时，我的项目遇到了问题。 Platform-26被指定两次。我已经从Android SDK的平台中删除了Plateform-26，但仍然显示错误

dependencies {
   compile project(path: ':HeaderListView')
   compile project(path: ':MPChartLib')
   //compile files('libs/okhttp-3.4.1.jar')
   compile('com.squareup.okhttp3:okhttp:3.7.0') {
    force = true
  }

 compile('com.squareup.okio:okio:1.10.0') {
    force = true

   }
   compile('com.peekaboo.connect:sdk:2.0.70') {
    exclude module: 'com.android.support:appcompat-v7'
    exclude group: 'com.facebook.infer'
  }
  //    compile(name: 'peekaboo-guru-sdk', ext: 'aar')
  //    compile project(':react-native-config')
  //    compile project(path: ':safetynetlib')
  compile 'com.android.support:appcompat-v7:26.0.2'
  compile 'com.android.support:support-v4:26.0.2'
  compile 'com.android.support:recyclerview-v7:26.0.2'
  compile 'com.android.support:design:26.0.2'
  //    compile 'com.google.android.gms:play-services-vision:9.8.0'
  compile 'com.android.support:multidex:1.0.1'
  compile 'com.squareup.picasso:picasso:2.5.2'
  compile 'de.hdodenhof:circleimageview:2.1.0'

  compile 'com.facebook.android:facebook-android-sdk:4.35.0'
   //    //Firebase
   compile 'com.google.firebase:firebase-core:16.0.0'
}  

以下为例外

  org.gradle.api.tasks.TaskExecutionException: Execution failed for task
