android - 将 Android Studio 2.3.3 更新到 3.0 后无法合并 dex

Question

Android Studio 3.0 更新后无法合并dex。 而且我还尝试了很多来自 stackoverflow 的老问题:-

• Error:Execution failed for task

• Android Studio 3.0 Unable to merge dex

但这对我不起作用。

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.

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

我的应用程序 gradle 文件如下:-

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '26.0.2'
    defaultConfig {
        applicationId "com.example"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 5
        versionName "1.4"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        multiDexEnabled true

        manifestPlaceholders = [onesignal_app_id: "One Signal Key",
                                onesignal_google_project_number: "REMOTE"]
    }

    lintOptions {
        checkReleaseBuilds false
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'

}
