Q. How can I export or import a Maven 2 format repository over HTTP into Nexus Repository Manager
Import into NXRM 3.23.0 Pro and newer
To import a Maven 2 format repository from a NXRM 2.x repository storage directory or equivalent Maven repository layout on disk ( ie. local ~/.m2/repository ) into 3.x, create a Repository - Import external files task and run it. More information can be found in the help documentation ( NEXUS-11468 ).
Import into NXRM 3.22.1 and earlier, including NXRM 3 OSS and NXRM 2.x
There is no formal repository export or import built into the these versions.
However you should be able to use a third party tool to do this over HTTP using standard request paths.
Option 1. Here is a third-party tool which does this:
Option 2. Another option is the transfer artifact command of the RiotGames nexus_cli.
Any problems with the above third-party tools should be directed to the tool author.
Export is planned only for a future NXRM 3 version. Please monitor NEXUS-23854 for updates.
