Maven只给我春季4.0.3的错误

Question

我的spring-project有问题。当我开始在我的pom.xml中添加dependnency时，我注意到我无法在版本4.0.3中添加类似spring-tx或spring-orm的依赖性.RELEASE，它的工作与我测试的所有其他版本 - 4.0.0.RELEASE - 4.0.5.RELEASE（当然没有0.3）。

我的pom.xml

Eclipse给我错误

ArtifactDescriptorException: Failed to read artifact descriptor for   
org.springframework:spring-tx:jar:4.0.3.RELEASE: ArtifactResolutionException: Failure to   
transfer org.springframework:spring-tx:pom:4.0.3.RELEASE from 
http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not
be reattempted until the update interval of central has elapsed or updates are forced. 
Original error: Could not transfer artifact org.springframework:spring-tx:pom:4.0.3.RELEASE 
from/to central (http://repo.maven.apache.org/maven2): null to 
http://repo.maven.apache.org/maven2/org/springframework/spring-tx/4.0.3.RELEASE/spring-tx-
4.0.3.RELEASE.pom

我检查了网址 http://repo.maven.apache.org/maven2/org/springframework/spring-tx/4.0.3.RELEASE/spring-tx-4.0.3.RELEASE.pom我看到xml那么为什么我得到错误null（＆lt; - this url）？

我只是好奇为什么我在我的项目中使用spring 4.0.3.RELEASE得到这个错误我改变了工作版本
