java - 对一个项目进行任何更改后,Maven 编译错误“找不到符号”
问题描述
好吧,我在同一时间用 maven 学习 JEE:p 我在 netbeans -> core ->frontoffice 中有这种项目结构
frontoffice 使用来自核心的类,所以我在 pom.xml 中添加了依赖项,如下所示:

核心项目 pom.xml 没有变化。一切正常我可以在前台使用核心项目的类,但是当我向核心类添加一些东西并清理和构建时。好的,但是当我在前台项目上清理和构建时,我得到了我添加的错误:

就像旧版本的类仍然存在,编译器编译它们而不是修改过的类。我试图清理项目和netbeans缓存,但同样的错误我不知道为什么会发生这种情况在我看来不合逻辑。
你能帮我找出问题所在吗?
