BSOD 后 Gradle 构建错误（java.lang.NullPointerException（无错误消息）

Question

在 BSOD（蓝屏死机）之后，我有下一个 gradle 构建错误： FAILURE：构建失败并出现异常。

• 出了什么问题：java.lang.NullPointerException（无错误消息）

• 尝试：使用 --info 或 --debug 选项运行以获得更多日志输出。

• 例外是：

构建失败

总时间：7.294 秒

P.S：我尝试清理项目、同步 gradle、重建项目，但这些都对我没有帮助。

Answer 1

我想，这可能是由损坏的 Gradle 缓存引起的。您可以尝试删除它，为此，您必须关闭 Android Studio，然后使用 gradle --stop 命令停止 Gradle 守护程序，然后从项目的根目录中删除 .gradle 文件夹。之后，您必须启动 Studio 并尝试重新构建它。

Answer 2

在 Android Studio/Intellij 中按 cmd + shift + a (ctrl + shift + a)，输入Invalidate caches，然后按 Invalidate and restart 按钮。

帮我搞定了

Answer 3

在这种情况下，“文件 -> 使缓存无效并重新启动”选项通常对我有帮助。
