Java版我是 Flutter 的新手，起初我的项目运行良好，但突然我开始遇到这个问题：FAILURE: Build failed with an exception。

  • 出了什么问题：任务“：app：processDebugMainManifest”执行失败。

无法使字段私有最终 java.lang.String java.io.File.path 可访问：模块 java.base 不会“打开 java.io”到未命名的模块 @1f05eb0a 现在每当我运行项目甚至尝试创建新项目时我收到这样的错误，我什至尝试了与此查询相关的可用答案，但未能调试它。这是我的颤振版本：

只是将 JDK 版本从 16 降级到 15 对我有用。
