无法读取com.sun.xml.ws:jaxws-rt:jar:2.2.8的工件描述符：UnresolvableModelException：无法传输com.sun.xml.ws:bundles:pom

Question

我正在关注http://memorynotfound.com/deploy-jaxws-application-tomcat-example/的例子。我刚刚将这个项目（作为Maven）导入工作空间，但我看到以下错误： -

    Description Resource    Path    Location    Type
        ArtifactDescriptorException: Failed to read artifact descriptor for 
    com.sun.xml.ws:jaxws-rt:jar:2.2.8: UnresolvableModelException: Failure to transfer com.sun.xml.ws:bundles:pom:2.2.8 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 
    com.sun.xml.ws:bundles:pom:2.2.8 from/to central 
(http://repo.maven.apache.org/maven2): connection timed out to http://repo.maven.apache.org/maven2/com/sun/xml/ws/bundles/2.2.8/bundles-
    2.2.8.pom   pom.xml /jax-ws-tomcat-example  line 1  Maven Dependency Problem

我在解决问题时非常疲惫，请帮助/指导。
