我下載Spring框架，並添加所需的所有罐子對我的項目但當我添加依賴我的pom.xml文件，並嘗試建立它給了我下面的錯誤該項目

Could not resolve dependencies for Project.... 

我的pom.xml的是

任何想法爲什麼我得到這個錯誤？

在此先感謝

Answer 1

按照MVN輸出行家不能取「http://repo.maven.apache.org/maven2/org/springframework/spring/2.5.6/spring-2.5.6.pom」。

但是，我現在可以用我的瀏覽器來獲取它。 這樣的事情可能是由網絡/代理問題引起的。

如果你的maven/proxying/dns配置沒有任何問題，我試圖用替代回購來解決dep的問題。 像這樣，例如：https://repository.jboss.org/nexus/index.html#welcome

此外，如果您想嘗試替代回購，這可能很方便。這裏是我的一個項目的存儲庫部分的複製粘貼：
