我使用maven在Java上开发了几天。其他人的项目编译好了。
今天,我使用新电脑并设置如上所述的env。
当我输入mvn eclipse:eclipse时,jar被下载了,但它没有附加到.classpath。

答案 0 :(得分:1)
嗯....主要的POM('org.sonatype.oss:oss-parent:2')存在于主Maven存储库中。所以下载它可能会出现短暂的问题。
查看您当地的maven repo(例如“〜/ .m2 / repository / ...”)以查看父POM是否存在,并检查Maven是否已下载损坏的副本。 (该POM文件与this page上看到的内容相同吗?
如果它已损坏,您可以尝试吹掉“... / 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如何配置上游存储库详细信息等。
