我已经收到源代码和说明，以在sonatype nexus中配置本地p2和maven存储库，将回购文件复制到sonatype-work / nexus / storage并以特定顺序在子文件夹中运行mvn install。 Maven存储库可以正常工作，但是尽管驱动器的相应文件夹中存在p2元数据文件（artifacts.jarartifacts.xml content.jar和content.xml），但nexus找不到它们，导致在nexus.log中记录以下错误（我将域名更改为companyname.com）：

当尝试运行mvn install时出现错误：
[INFO] Adding repository http://127.0.0.1:8081/nexus/content/repositories/eclipse-luna
[ERROR] Failed to resolve target definition /home/creotech/.m2/repository/COMPANYNAME/maven/Eclipse-Luna/1.0.0-M1/Eclipse-Luna-1.0.0-M1.target: Failed to load p2 metadata repository from location https://COMPANYNAME.COM/nexus/content/groups/eclipse-luna/: No repository found at http://127.0.0.1:8081/nexus/content/repositories/eclipse-luna. -> [Help 1]
我可以在浏览器http://127.0.0.1:8081/nexus/content/repositories/eclipse-luna中打开，然后看到文件和文件夹：
我可以打开子文件夹，也可以从浏览器中下载子文件夹中的文件，但是由于错误，我无法下载根目录（工件/内容jar / xml）中的任何文件：
404 - Item not found for request "ResourceStoreRequest{requestPath='https://COMPANYNAME.COM/nexus/content/groups/eclipse-luna/content.xml', requestContext=RequestContext{this=org.sonatype.nexus.proxy.RequestContext@c1bae82, parent=null}, pathStack=[], processedRepositories=[], appliedMappings={}}" in repository ""Eclipse - Luna" [id=eclipse-luna]"!

我尝试更改关系的存储库列表以及“管理”>“服务器”中的超时时间，但没有帮助。为确保文件权限不是问题，我将权限更改为777并以root用户身份运行nexus，但它也没有帮助。另外，我尝试在此存储库以及所有存储库中依次运行任务“重建P2元数据和重建P2存储库”，但是在两种情况下，问题均保持不变。从nexus-2.14.0-01升级到2.14.9-01也没有更改与wrapper.conf中java max memory增量相同的任何内容。有什么解决方法的想法吗？

如果有人会遇到类似的问题-托管站点存储库已解决上述问题
