Announcing GoNexus


Today Sonatype is announcing our official Sonatype Go proxy -

The Sonatype product team attended GopherCon 2019 and it was clear to us that the excitement around the Go programming language is palpable. It was also clear that the ecosystem has reached that point in its maturity where developers want more reliable builds and therefore need Go packages to be immutable, predictable and always available.

Successfully running the Central Repository for Java (Maven Central) since 2002, our team at Sonatype understands this problem better than any other company. This year more than 3.7M unique Java open source software components were released into the Central Repository. We’re now turning our attention to Go. So far this year we’ve contributed Nancy, Goalie, Nexus Repository OSS, and DepShield to the Go community. The open source Nexus CLI is currently being developed in the Nexus community on GitHub, too. GopherCon made us want to do more. GoNexus is the next step to help developers run reliable and reproducible builds.

If you are interested in immutable, re-usable Go modules and using a proxy run by the leading organisation in this space, then I encourage you to set your GOPROXY environment variable to (“export GOPROXY=”)

Nexus Repository Manager

The Go community announced a great proxy tool called Project Athens, which is currently in beta, and has been instrumental in helping developers transition to Go Mod. Sonatype has a similar product, Nexus Repository Manager, which is the most used universal repository manager and includes support for the Go programming language. I encourage you to download Nexus Repository Manager OSS for free and make use of GoNexus by creating a proxy repository with remote URL
