我正在使用nexus 来托管我的maven 存储库，并且maven 命令行（win32 和linux）可以使用相同的命令和相同的setting.xml 成功地从这个nexus 传输工件。但是m2e会失败如下：
[WARNING] Could not transfer metadata m3-app:m3:1.0-SNAPSHOT/maven-metadata.xml from/to Nexus (http://1.2.3.4:8080/nexus/content/groups/public): Failed to create a selector. to http://1.2.3.4:8080/nexus/content/groups/public/m3-app/m3/1.0-SNAPSHOT/maven-metadata.xml
[WARNING] Failure to transfer m3-app:m3:1.0-SNAPSHOT/maven-metadata.xml from http://1.2.3.4:8080/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of Nexus has elapsed or updates are forced. Original error: Could not transfer metadata m3-app:m3:1.0-SNAPSHOT/maven-metadata.xml from/to Nexus (http://1.2.3.4:8080/nexus/content/groups/public): Failed to create a selector. to http://1.2.3.4:8080/nexus/content/groups/public/m3-app/m3/1.0-SNAPSHOT/maven-metadata.xml
我已经测试了服务器，而 eclipse 无法抓取工件，我的浏览器可以成功获取元数据 xml。m2e有问题吗？
更新：我的项目包括大约 35 个 jar，前几个 jar 会成功，后来会失败。
