[编程] qt 新手求助： No documents matching ‘ui_mainwindow.h’ could be found

新手上路，整了一个非常单纯的小工程（拿 ai 写的），然后在 ui 设计时右键 Pushbutton 转到槽时被这个问题干碎了，一头雾水，甚至不知道怎么排除错误。

编译日志如下：

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use ‘–warning-mode all’ to show the individual deprecation warnings and determine if they come from your own scripts or plugins.
