常 Spring 藤无法解决依赖关系，而它适用于maven

我作为一个Maven新手，我正在玩我自己的本地Sonartype Nexus . 我已经配置我的maven安装使用它作为代理，它适用于一个简单的测试项目解决我的 pom.xml 中的以下依赖项

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>3.1.2.RELEASE</version>
</dependency>

接下来，我和Ivy一起尝试了一个类似的项目

在 ivy.xml . Ivy使用相同的Nexus服务器作为代理（在 ivysettings.xml 中配置）

<ivysettings>
    <settings defaultResolver="default"/>
    <property name="m2-pattern" value="${user.home}/.m2/repository/[organisation]/[module]/[revision]/[module]-[revision](-[classifier]).[ext]" override="false" />
    <resolvers>
        <chain name="default">
            <ibiblio name="public" m2compatible="true" root="http://localhost:2281/nexus/content/groups/public"/>
        </chain>
    </resolvers>
</ivysettings>

但是，运行ant时，无法解析 hibernate-validator-4.2.0-Final

我已经尝试在Nexus安装中添加更多远程存储库，例如SpringSource Enterprise Bundle Repository（http://maven.springframework.org/release/）或JBoss public（https://repository.jboss.org/nexus/content） / repositories / releases /）但这没有帮助 .

原则上，Ivy似乎也能正常工作，因为它在失败之前会获取许多其他依赖项 .

我的问题：1）为什么Maven没有因为同样的原因而失败？ hibernate-validator是可选的，Ivy还有另一个解决策略Maven吗？

2）我很好奇它试图解决的工件名称： org.hibernate#com.springsource.org.hibernate.validator;4.2.0.Final （顺便说一句，如果我添加 <dependency org="org.hibernate" name="hibernate-validator" rev="4.2.0.Final" /> 它可以工作，但对于Spring案例，它需要工件 com.springsource.org.hibernate.validator ？
