BUILD FAILED

我已经在这个项目上工作了将近一年，这是我第一次看到使用 Gradle 构建这个问题。 Google 也不会返回任何有用的结果。

我的电脑硬盘停止响应，所以我不得不在 Android Studio 打开时强制关机，这可能与问题有关。

采取的步骤：

• 重启 Android Studio

• 使缓存无效并重新启动

• 删除我的主目录中的 .gradle 文件夹

这很烦人，我似乎找不到解决办法。感谢您的帮助！

Answer 1

您是否尝试过清理项目并重新运行？

Answer 2

这应该可行：

1. 从工作区中删除 .gradle 文件夹。
2. 重启 Android Studio。
3. 构建 -> 清理项目。

Answer 3

您只需点击构建 -> 重建。就是这样。

Answer 4

构建 -> 清理项目。而不是建造 -> 重建项目

Answer 5

不是真正的解决方案，但我将构建变体从 debug 切换到 release，它能够正确完成构建。

因此，如果debug 不是优先级，那么切换构建变体无论如何都可以帮助您构建。

Answer 6

我最终通过删除项目目录并从 Github 的旧版本重新导入项目来修复它。这不是一个很好的解决方案，但它是唯一有效的解决方案。我有幸在 Github 上备份了我的代码

Answer 7

另一种可能的解决方案是再次将项目导入 Android Studio，方法是将源代码检出到干净的位置，或者仅删除项目根目录下的 .idea 目录，然后重新导入。

当然，先备份。

另外，另一个想法可以是首先重新启动计算机。如果是 Windows，在某些情况下，我会看到一些文件被锁定，从而导致奇怪的行为。

Answer 8

对于 Firebase android 项目，

如果您在移动应用中使用 Firebase。

下载google-services.json 文件并将其放入/app 文件夹并再次运行该项目。

Answer 9

对于 Cordova 项目，首先保存（或获取，如果您还没有）google-services.json 文件，以及您可能对 Android 平台文件夹进行的其他配置，然后运行：

cordova platform remove android

之后，再次相加：

cordova platform add android

将您的google-services.json文件保存在platforms/android/app文件夹中，然后尝试构建APK。它对我有用，用于修复错误：

Execution failed for task ':app:processDebugGoogleServices'.
> Malformed root json

Answer 10

构建 => 清理项目 等到同步 构建 => 重建项目 重启安卓工作室
