Android Studio 无法运行教程应用程序。任务 ':app:dexDebug' 执行失败。 jdk1.8.0_25\bin\java.exe' 以非零退出值 2 完成

Question

我是 Android Studio 的新手，所以在解释可能的解决方案时请说清楚，我不熟悉这个环境。

出于某种原因，当我运行一个示例应用程序时，构建总是失败并出现异常。 Gradle 控制台始终在运行时间显示以下消息：

     FAILED

    FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':app:dexDebug'.
    > com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command 'C:\Program Files\Java\jdk1.8.0_25\bin\java.exe'' finished with non-zero exit value 2

    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

是什么导致了 "Execution failed for task ':app:dexDebug'" 错误，我怎样才能让 Android Studio 让我运行我的应用程序？

Answer 1

在我的例子中，当有 2 个或更多库发生冲突时（相同的库但不同的版本），我得到了这个错误。在依赖块中检查您的应用 build.gradle。

检查库，我记得当我有多个模块使用 support-v4 和 support-v13 时遇到过这个问题。我删除了 support-v4，它似乎解决了我的问题。

转到文件->项目结构。检查每个模块的依赖关系。
