顶级构建文件：

       // Top-level build file where you can add configuration options common to all sub-projects/modules.

   buildscript {

       repositories {

           jcenter()
           maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
           maven { url 'https://maven.fabric.io/public' }

       }
       dependencies {
           classpath 'com.android.tools.build:gradle:3.2.0-alpha01'

   }

   allprojects {

           google()
           jcenter()
           maven { url "https://jitpack.io" }
           flatDir {
               dirs 'libs'
               dirs project(':app').file('libs')
           }

       }

   }
   task clean(type: Delete) {
       delete rootProject.buildDir
   }

编译项目时得到的完整错误是：

失败：构建因异常而失败。



出了什么问题：   任务执行失败＆＃39;：app：transformDexArchiveWithExternalLibsDexMergerForDebug＆＃39;。   java.lang.RuntimeException：com.android.builder.dexing.DexArchiveMergerException：无法合并dex



尝试：   使用--stacktrace选项运行以获取堆栈跟踪。使用--info或--debug选项运行以获取更多日志输出。使用--scan运行以获得全面的见解。

完整错误如下：

Answer 1

我遇到了同样的问题。您可以尝试的一件事是Clean Project，然后是Rebuild Project。它对我有用。

Answer 2

尝试从File > Invalidate Caches / Restart清除干净的android studio缓存。它对我有用
