java - 为什么我收到 PluginResolutionException？

Question

我正在使用 NetBeans 7.0，默认情况下有 Maven 3.0.3...上周我打开了一个使用 Maven 2.2 开发的项目...现在即使关闭该项目...NetBeans 不允许我创建任何新项目...甚至 NetBeans 的示例项目也不允许...每次我收到以下错误...

    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:

任何有关此问题的帮助将不胜感激......

提前致谢，，
