Execution failed for task ':react-native-custom-tabs:transformDexArchiveWithExternalLibsDexMergerForDebugAndroidTest'

Question

I am trying to build ./gralde assembleAndroidTest and the result is an error

FAILURE: Build failed with an exception.

What went wrong:

Execution failed for task ':react-native-custom-tabs:transformDexArchiveWithExternalLibsDexMergerForDebugAndroidTest'.

java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

Following is my project gradle details:

app/build.gradle

androidTestImplementation(project(path: ":detox"))
androidTestImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.1'
androidTestImplementation 'com.android.support.test:rules:1.0.1'
ext {
    supportLibVersion = "27.0.2"
    playServicesVersion = "11.8.0"
    reactNativeVersion = "0.53.3"
}

android/build.gradle:

ext {
    compileSdkVersion = 27
    buildToolsVersion = "27.0.2"
    targetSDKVersion = 27
    minSDKVersion = 21
}

react-native-custome-tabs/build.gradle:

android {
        compileSdkVersion 25
        buildToolsVersion "25.0.1"

        defaultConfig {
            minSdkVersion 16
            targetSdkVersion 23
            versionCode 1
            versionName "1.0"
        }
    }
    dependencies {
        compile "com.facebook.react:react-native:+"  
        compile 'com.android.support:customtabs:25.0.1'
        compile ('com.github.droibit.customtabslauncher:launcher:1.0.8') {
        exclude module: 'customtabs'
        }
        testCompile 'junit:junit:4.12'
        }

I am getting conflict error message in both build.gradle
