我已经使用maven在Java中开发了几天了。把项目交给别人编译就ok了。
今天，我用了一台新电脑，并像上面那样设置了环境。
当我输入MVN eclipse:eclipse时，jar被下载了，但它没有附加到。classpath。
c:idlecenter>call mvn clean eclipse:eclipse -DdownloadSources=tru

嗯....父POM ('org.sonatype.oss:oss-parent:2')存在于主Maven仓库中。所以可能是下载时出现了暂时的问题。
查看您的本地maven repo(例如。"~/.m2/repository/…")来查看父POM是否在那里，并检查Maven是否下载了损坏的副本。(该POM文件是否与您在此页面上看到的相同?
如果它损坏了，你可以试着删除"…/org.sonatype.oss/…"子树并再次运行Maven。如果您仍然看到Maven失败，那么您可能需要检查您如何配置您的上游存储库细节，等等。
