Java 将当前项目转换为Maven的问题

我正在将当前项目转换为Maven项目。单击“转换为Maven”后，我得到以下错误信息

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'ActiTime'.
Could not calculate build plan: Plugin org.apache.maven.plugins:maven-resources-plugin:2.5 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-resources-plugin:jar:2.5

我已经添加了POI、POI ooxml、Selenium、testNg依赖项，但现在我得到了

ArtifactDescriptorException: Failed to read artifact descriptor for org.seleniumhq.selenium:selenium-java:jar:2.48.2: ArtifactResolutionException: Could not transfer artifact org.seleniumhq.selenium:selenium-java:pom:2.48.2 from/to central (http://repo.maven.apache.org/maven2): connection timed out to http://repo.maven.apache.org/maven2/org/seleniumhq/selenium/selenium-java/2.48.2/selenium-java-2.48.2.pom

有人能调查一下吗 我使用EclipseKeepler作为ID和JDK1.7

下面是POM.XML的屏幕截图和错误。请参考这个

您是否有internet连接？为什么要修改settings.xml？您也可以在pom.xml中添加存储库位置。请参阅：）默认情况下，settings.xml不是必需的，当您要覆盖存储库设置时，它是必需的，因此请将其删除并重试。如果您只是在浏览器中粘贴，这是否有效（您会看到一长串链接）？您是否使用eclipse中的Build project选项构建项目？尝试ALT+SHIFT+X和M组合，它会要求您提供一个选项（目标）指定干净安装并以这种方式运行，让我知道发生了什么，而且依赖项错误是针对maven资源插件的，我在pom中看不到。刷新（F5）项目并更改工作空间设置。（转到首选项->工作区->使用本机钩子）@RahilKumar您无法找到它，您必须手动编写它。也可以尝试ALT+F5（右键单击project->Maven->更新项目配置）
