Android应用程序生成错误。无法合并索引[重复]

错误:任务“:app:transformDexArchiveWithExternalLibsDexMergerForDebug”的执行失败。 Java语言lang.RuntimeException:com。安卓建设者德兴。DexArchiveMergerException:无法合并dex

我使用的是Android Studio的3.0.1版。

我还尝试了“清理项目”和“重建项目”。

*项目构建梯度

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.3'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    }
}

*模块构建梯度

当我执行重建项目时,会出现如下错误。
