Multidex enabled - still unable to merge dex

Question

this is my 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
}

this is my Manifest.xml

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

these are my dependencies

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'
    //noinspection GradleCompatible
    implementation 'com.android.support:recyclerview-v7:27.1.0'

    implementation 'com.google.firebase:firebase-messaging:11.8.0'
    implementation 'com.google.firebase:firebase-crash:11.8.0'

    implementation 'com.google.maps.android:android-maps-utils:0.4.4'
    implementation 'com.google.code.gson:gson:2.8.2'

    implementation "org.jetbrains.anko:anko:0.10.4"
    implementation "org.jetbrains.anko:anko-design:0.10.4"

    //    CircleImage
    implementation 'de.hdodenhof:circleimageview:2.1.0'
    //    Glide
    implementation 'com.github.bumptech.glide:glide:4.5.0'
    //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')
}

still gradle build fails because of

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

can someone please figure out why? I am 2 days into this problem and I still have no solution

 Exception is:

Look in the Gradle Console for a full Java stack trace associated with this build error. If you see one, it should have more details in it of specifically what is going wrong. If you do not see one, try a command-line build where you include `--stacktrace` to force the stack trace to appear. See [this question and answer](https://stackoverflow.com/q/49076888/115145) for an example of what I am referring to. — CommonsWare, Mar 12 '18 at 10:58
for API 21+ there is no need to add multidex lib as dependency and no need to extend your app from android.support.multidex.MultiDexApplication, that line in buildConfig is enough : https://developer.android.com/studio/build/multidex.html#avoid — Viktor Yakunin, Mar 12 '18 at 11:02
check your manifest file, any activity or permission added in two times — RejoylinLokeshwaran, Mar 12 '18 at 11:06
implementation project(path: ':regservice') this one is problem, remove this and build — RejoylinLokeshwaran, Mar 12 '18 at 11:21

Create application class like,

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

use "MyApplication" instead of android.support.multidex.MultiDexApplication

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