android - 在 macOS Catalina 中构建 Android 原生教程项目失败

Question

我根据 Android 教程创建了一个原生 Android C++ 项目。我收到以下编译错误:(在 macOS Catalina 中)

> Task :app:javaPreCompileDebug

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:externalNativeBuildDebug'.
> Build command failed.
