我使用acegi 插件 0.5.2创建了一个grails 1.2.0项目，效果很好。

要将项目集成到我们的公司构建基础架构中，我需要通过 maven 构建它。所以我使用grails maven 集成将它转换为一个 maven 项目，它也运行得很好。

有一个问题：我有一个实现GrailsUser接口的 Java 类 CustomUserDetails。当 maven 尝试编译项目时，它找不到GrailsUser接口类，它是acegi 插件的一部分。

我是否遗漏了某些东西，或者 grails maven 集成是否存在导致类路径中缺少插件类的问题？

更新：这是我项目的 pom.xml：

我认为正在发生的事情是您期望在编译项目源代码时可以使用插件类路径。插件有自己的类加载器，所以你的类不会看到里面的东西。

而是为包含 GrailsUser 接口的库定义项目依赖项，并确保该依赖项的范围是 compile（默认）。
