未添加到Maven的Grails acegi插件類

Question

我創建了一個grails 1.2.0項目，使用了acegi插件0.5.2，這非常有效。

要將項目整合到我們公司的基礎架構中，我需要通過maven構建它。所以我使用grails maven integration將其轉換爲maven項目，這些工作也非常好。

有一個問題：我有一個Java類CustomUserDetails，它實現了GrailsUser接口。當maven試圖編譯該項目時，它找不到接口類，它是acegi插件的一部分。

我是否錯過了某些東西，或者是否存在導致類路徑中缺少插件類的grails maven集成的問題？

更新：這裏是我的項目的pom.xml：

我認爲正在發生的事情是你期待的類路徑的插件可用編譯你的項目的源代碼時。插件有自己的類加載器，所以你的類不會看到那裏的東西。

相反，將一個項目依賴項定義到一個包含GrailsUser接口的庫，並確保該依賴項的範圍是compile（默認值）。
