【Android】Failed to capture snapshot of output files for task
本文环境：
- Android Studio 3.0.1
- Gradle version 4.6
- Android Plugin Version 3.0.1
一、问题描述
新建了一个 Android 项目，minSdkVersion 选的 21（Android 5.0），啥都没改呢就编译报错，很是诡异，如图所示
Gradle tasks [:app:assembleDebug]
Failed to capture snapshot of output files for task 'transformClassesWithDexBuilderForDebug' property 'streamOutputFolder' during up-to-date check.
> Failed to create MD5 hash for file 'C:\User\Administrator\Desktop\android\MyApplication\app\build\intermediates\transforms\dexBuilder\debug\6.jar'.

二、解决方案
经过一番尝试和搜索，终于找到了类似问题，发现了解决方案，原来是 Instant Run 的锅，设置里关闭就好了。
三、问题原因
据 Stack Overflow 描述，貌似是 gradle 的问题，还有一种可能就是杀毒软件的问题
The issue in the latest android studio update is with the Instant Run feature. There happens to be a serious issue with gradle, so you may either turn off the Anti-Virus or the Instant Run feature till then.
