android - 已启用 Multidex - 仍然无法合并 dex

Question

这是我的build.gradle

android {
compileSdkVersion 27
defaultConfig {
    applicationId "xxxx.xxxx.xxxx"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

这是我的 Manifest.xml

 <application
    android:name="android.support.multidex.MultiDexApplication"
.../>

这些是我的依赖

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
    implementation fileTree(include: ['*.jar'], dir: 'libs')


    implementation 'com.android.support.constraint:constraint-layout:1.0.2'

    //    Glide

    //DateTimePicker
    implementation 'com.wdullaer:materialdatetimepicker:3.4.0'

    implementation 'org.ocpsoft.prettytime:prettytime:4.0.1.Final'


    implementation 'com.github.kittinunf.fuel:fuel-android:1.12.0'


    implementation 'com.seatgeek:placesautocomplete:0.3-SNAPSHOT'



    implementation project(path: ':regservice')
}

gradle 构建仍然失败，因为

Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'. java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

请问有没有大佬知道这是为什么？ 我已经解决这个问题 2 天了，但我仍然没有解决方案

像这样创建应用程序类，

  public class MyApplication extends Application {
  @Override
   protected void attachBaseContext(Context base) {
      super.attachBaseContext(base);
      MultiDex.install(this);
   }
  }

使用“MyApplication”代替 android.support.multidex.MultiDexApplication

<application
android:name=".MyApplication"
 />
