This repository is defined in a pom.xml of a dependency.

Good idea.

apache-snapshots is not in the public group by default, although it is in
Nexus as a repository. You can edit the public group members and add
apache-snapshots as a member.

Search indexes have nothing to do with an artifact being able to be
downloaded.

Yes, the maven-site-plugin was referencing apache/snapshots in its 
 section. Yet another tangle with 'dependency hell'





So, then I configure nexus to mirror
https://oss.sonatype.org/content/groups/public and I add to my
settings.xml

  

  nexus

  http://localhost:8081/nexus/content/groups/public

  


Good idea.

apache-snapshots is not in the public group by default, although it is 
in Nexus as a repository. You can edit the public group members and 
add apache-snapshots as a member.




Taking apache-snapshots offline in my Nexus configuration was one of the 
first things I did, but the problem was stemming from maven-site-plugin.

In my case, I forgot to add sonatype-oss to the public group in Nexus. A 
better Nexus GUI would ask the user if they wanted to add a newly 
created remote repo to the public group. I have been caught by this 
problem more than once, and the diagnostics around the problem are not 
very good.

Thanks Frank, I added what you suggested to my settings.xml, but the 
problem turned out to be that I forgot to add sonatype-oss to the public 
group.


I have been caught by that problem in the past, as I recall, and a 
better UI would ask you if you wanted to add a newly created remote repo 
to public when you created it.


Cheers, Eric

You did not have any credentials in your (I assume) settings.xml.

The problem with the apache.org repo might be caused by missing the

I have the following

true


true

https://oss.sonatype.org/content/groups/public

  

But when I run maven I get

[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-site-plugin:3.3:site (default-site) on project

(http://repository.apache.org/snapshots) -> [Help 1]

Why in the world is it looking in http://repository.apache.org/snapshots ???

So, then I configure nexus to mirror 
https://oss.sonatype.org/content/groups/public and I add to my settings.xml

  

  nexus
  *
  http://localhost:8081/nexus/content/groups/public

  

and then I get

I know this to be a lie because when I go through the nexus UI I can clearly 
see the artifact in question in both the nexus index and storage. However, for 
some reason, the artifact pom.xml is neither in the index nor storage. When I 
go to 
https://oss.sonatype.org/content/groups/public/net/trajano/wagon/wagon-git/1.0.1-SNAPSHOT/
 I can clearly see the pom.xml with the other files that nexus has downloaded. 
Why is nexus refusing to download the pom.xml?
