task.app:transformDexArchiveWithExternalLibsDexMergerForDebug'com.android.builder.dexing.DexArchiveMergerException失败：无法合并dex

Question

我尝试添加multiDexEnabled trur，但它仍然面临上述问题。怎么解决呢？ 我正在使用3.1版Android Studio。

android {
    compileSdkVersion 26
    defaultConfig {
        applicationId "com.moon.administrator.librarytest"
        minSdkVersion 23
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation 'com.android.support:appcompat-v7:26.1.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
