为什么Maven下载不同版本的Spring构件？

在我的Maven项目中,我定义了很多Spring依赖项,并且我注意到在某些情况下,即使在pom.xml中指定了相同的版本,它们也会选择不同版本的工件.

这是mvn依赖项的概述：树

[INFO] com.vrutberg.blogping:blogping:war:1.0-SNAPSHOT

[INFO] \- com.sun.jersey.contribs:jersey-spring:jar:1.12:compile
[INFO]    \- com.sun.jersey:jersey-servlet:jar:1.12:compile

在我的pom.xml中,我定义了一个在所有Spring工件上使用的属性,其定义如下：

<org.springframework.version>3.0.5.RELEASE</org.springframework.version>

这些是我的依赖项：

    <!-- spring libraries -->

        <artifactId>spring-test</artifactId>

    </dependency>

为什么到底使用了不同的版本？

编辑：

好的,所以我刚刚发现了这些警告.我想这与它有关：

为什么某些人造物缺少绒球？为何退回到使用3.0.0.RC3？

最佳答案

在eclipse中,至少在上一个版本中,有一个pom视图,您可以在其中查看依赖关系树,以便找出为什么要添加一个库作为其他库的安全性.
