Plugin does not work with groups

[ieugen]

Hello,

How can I access artifacts in a private repository. In the UI I can authenticate and see them.
Using the old plugin, I could have added the credentials to the url like: https://user:passord@host.com/path/to/resource?r=....

I'm using nexus 3.6 .

btw. Is there a way to check if the plugin works? I have tried to get a public artifact and returns emtpy json array.

Thanks,

[ieugen]

I found it works with proxy repositories but not with groups.

The plugin does not work with groups.

As a feature enhancement, it would be great if it works with groups as well. We use rundeck to deploy and it would be usefull to be able to choose from snapshots and releases on some machines.

group not working?

[chenlingmin]

You can this.
I'm a bit busy, I don't have time to test it. Can you help me?
After that, commit pr for me.
Thanks 😂

I'll give it a shot today and get back with results.

p.s. Do you think we can improve plugin install/upgrade? I saw that for some plugins you can drop them in deploy folder and it works [1] .

[chenlingmin]

Very good. Have you tried it?

[ieugen]

Yes. I'm using it already. One thing that I noticed is that for SNAPSHOT I get the instance versions and not the SNAPSHOT version.

This has some downsides. I think it would be great to have an URL parameter to choose between getting the instance version or the SNAPSHOT.

[Blacktiger]

FYI, the SNAPSHOT version is stored in the repository attributes (attributes.maven2.baseVersion).
