NexSync

NexSync, a Go tool to synchronize repositories and artifacts to and from Nexus2/Nexus3 Artifact Servers. Able to synchronize Maven2 artifacts and artifact versions between repositories.

Currently capable of:

  • synchronizing artifacts between repos in Nexus3
  • synchronizing artifact versions from repos in Nexus2/Nexus3 to repos in Nexus3

Tool was originally created for automatic artifact mirroring.

Inspired by N3DR.

Installation

Build from source.

git clone https://github.com/marsskop/nexsync.git
cd nexsync
go build -o ./ ./..

Sync repos between Nexus3 servers.

./nexsync sync --urlfrom="<repo URL to sync from>" --repofrom="<repo to sync from>" \
    --userfrom="<user with download permissions>" --passfrom='<password for userFrom>' --tmpdir="./tmp" \
    --urlto="<repo URL to sync to>" --repoto="<repo to sync to>" \
    --userto="<user with upload permissions>" --passto='<password for userTo>'

Sync artifact versions fron Nexus2 to Nexus3 server.

./nexsync syncartifact --urlfrom="<repo URL to sync from>" --repofrom="<repo to sync from>" \
    --userfrom="<user with download permissions>" --passfrom='<password for userFrom>' --tmpdir="./tmp" \
    --urlto="<repo URL to sync to>" --repoto="<repo to sync to>" \
    --userto="<user with upload permissions>" --passto='<password for userTo>' \
    --artifact="<groupID>/<artifactID>" --fromnexus2

Why?

No tools that I could find (N3DR, nexus_cli, repositorytools, nexus3_cli) are capable of mirroring artifacts between Nexus Artifact Servers of different versions.
