为什么我要获取PluginResolutionException？

Question

我正在使用NetBeans 7.0，默认情况下它的maven 3.0.3。上周我打开了一个使用Maven 2.2开发的项目...现在，即使在关闭该项目之后..NetBeans不允许我创建任何新的project...not，即使是NetBeans的示例项目……每次我得到下面的错误...

    Plugin org.apache.maven.plugins:maven-resources-plugin:2.4.3 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.4.3: Could not transfer artifact org.apache.maven.plugins:maven-resources-plugin:pom:2.4.3 from/to central (http://repo1.maven.org/maven2): Error transferring file: repo1.maven.org: Unknown host repo1.maven.org -> [Help 1]

    To see the full stack trace of the errors, re-run Maven with the -e switch.
    Re-run Maven using the -X switch to enable full debug logging.

    For more information about the errors and possible solutions, please read the following articles:

任何关于这方面的帮助都将不胜感激……

先谢谢你，，
