Migrate from sonatype nexus to bintray

votes

Bintray seems to be a nice service and has many articles on how they are better than using Nexus, but for some reasons there are no migration scripts or tools to actually move artifacts from Nexus to Bintray. I'm looking for a solution for migrating a Nexus repository (either private or public) to Bintray without much hassle.

I'm aware that Bintray has REST API and it seems to be that you could just write a script that can create project versions and then upload artifacts from Nexus one by one, but for some reason I keep getting errors from this REST API and can't come with something that actually works.

REST API is indeed the way. Can you post some specific errors that you get and we'll get you going? - JBaruch

@JBaruch I posted my final script, hopefully it will help others, or might be a beginning of migration tool. It helped me at the end, and I resolved issues I had with API. - dant3

Currently there is no dedicated tool for that kind of migration. REST API is indeed the way to do it.

as @JBaruch already mentioned there is no tool to do that, so I had to write script which would do this. Script might be super flaky, slow and hard to maintain, so use with care. Also note that script is quite basic and you might be required to fix some stuff afterwards by hand.
