爲什麼m2eclipse從Eclipse構建路徑中排除資源？

我正在嘗試m2eclipse，Maven的Eclipse插件，並且已經注意到資源現在被排除在我所有項目的構建路徑之外。爲什麼m2eclipse從Eclipse構建路徑中排除資源？

我見過a question on the M2Eclipse FAQ page似乎處理這個確切的問題，但答案（釋義）似乎是說，這是故意允許資源過濾，一切都應該工作。

但是，當我在Eclipse中運行我的應用程序時，依賴項目中的大量資源無法通過我的應用程序找到。

我已經嘗試過我平時的Eclipse揮手 - 橡皮雞行動（清理所有項目，以 - 清潔開始）無濟於事。我確定我錯過了一些相當簡單的事情。有沒有人有什麼建議？

編輯：在m2控制檯中進行了一些挖掘，發現其中一個項目的構建不正確。當它試圖在用於構建其中一個項目的自定義插件中查找org.apache.maven.plugin.MojoFailureException時，我得到一個ClassNotFoundException。

在常見問題中提到的資源過濾運行。在實踐中，我發現這比Maven構建器的運行速度慢得多，而且只有在配置時纔會運行（默認情況下僅在完整版本中），這讓您不知所措，不知道爲什麼變化沒有拿起。

我傾向於修改Eclipse類路徑以包含src/main/resources。這對大多數用例來說已經足夠了。

對於簡單的方法不起作用的情況（例如，如果一個依賴項目有一些複雜的資源處理），我按照Robert的建議做，並關閉工作區解析，然後將依賴項安裝到本地存儲庫，包含在Maven類路徑容器中。

嘗試在嵌入式（3.0 AFAIK）Maven運行時和用於執行構建（本地安裝）的運行時之間切換。每當Maven的助洗劑對項目運行

感謝您的建議 - 我已經嘗試過這一點，它沒有任何區別。 – 2009-08-06 08:46:06

您是否嘗試過關閉工作區分辨率？然後，您將根據存儲庫中已安裝的工件構建每個項目。 – 2009-08-06 08:58:06
