我是Spring的新手,我将在春季开发我的第一个Helloworld应用程序。 我用的是什么
Spring 2.5.6
JDK 1.7
Eclipse 3.6
的Maven
我下载了Spring框架并将所有必需的jar添加到我的项目中,但是当我将依赖项添加到我的pom.xml文件并尝试构建项目时,它会给我以下错误
Could not resolve dependencies for Project....
我的pom.xml是

我知道为什么会收到此错误?
提前致谢
答案 0 :(得分:0)
根据mvn输出,maven无法获取“http://repo.maven.apache.org/maven2/org/springframework/spring/2.5.6/spring-2.5.6.pom”。
但是,我现在可以使用我的浏览器来获取它。 这样的事情可能是由网络/代理问题引起的。
如果您的maven / proxying / dns配置没有任何棘手的问题,我会尝试使用备用仓库来解决您遇到麻烦的问题。 像这样,例如:https://repository.jboss.org/nexus/index.html#welcome
此外,如果您想尝试替代回购,这可能会很方便。以下是我的一个项目的存储库部分的复制粘贴:
