找不到apache的公共類 - 在添加jar之後

我創建了一個項目，它使用apache commons validations.I測試了它作爲一個項目，並且每件事都按預期工作。找不到apache的公共類 - 在添加jar之後

然後，我創建了這個項目的jar文件。我已經檢查過，apache commons validations jar也被編譯並添加（作爲依賴）到我正在構建的jar中。

然後，我已經包含了這個jar（與Maven）到其他項目，並BANG錯誤！這裏是：

java.lang.NoClassDefFoundError: org/apache/commons/validator/routines/EmailValidator

我做錯了什麼？

這裏是堆棧跟蹤：
