android studio重建错误：找不到Gradle任务来构建为什么？

Question

我有一个带有清单文件的 android studio 项目，问题是当我同步 gradle 时出现以下错误

Gradle sync failed: Cannot get property 'sync' on null object

这也是个例外

    A problem occurred evaluating root project 'projectname'.

Answer 1

我尝试从我的settings.gradle 或settings.gradle.kts 文件中重命名并删除带有include ':app' 的行，将项目与Gradle 文件同步并恢复删除的行并再次同步。但它对我不起作用，对我有用的是；

1. 删除文件夹 [build、.idea、.gradle]
2. 重新同步或使缓存无效/重新启动
3. 并通过删除 include ':app' 等执行相同的步骤。

注意：这适用于我配置了 .kts 文件的项目
