Sonatype Nexus proxy problems

[Jonas Eriksson]

Hi,

 

We are in progress of proxying all repositories needed to build our sakai. We have setup a Sonatype Nexus 2.11.4-01 and it works great for many repositories, but not for the Sakai Maven Repository. It’s the same with snapshot and plugin repo.

 

Are the Sakai repos preventing use of a proxy like sonatype nexus?

 

Settings in our nexus:

 

Repository ID: sakai-maven2

Repository Name: Sakai Maven Repository

Repository Type: proxy

Repository Policy: Release

Repository Format: maven2

Contained in groups:

 

Remote URL: http://source.sakaiproject.org/maven2/

 

Status:

 

Status:

Unsuccessful.

Message:

No scraper was able to scrape remote (or remote prevents scraping).

Last run:

Mon Feb 22 2016 12:41:31 GMT+0100 (Central Europe Standard Time)

We're running an older version of Nexus.

We have a copy of Nexus proxying the Sakai repository without any
perceivable problems.

All our settings look the same, except we are connecting to it on
https rather than http and we don't have remote indexes enabled on
this repository.

Hi Jonas

We are also using an older version of Nexus, with exact same settings (we are also using http, not https)

Not having any issues...

Thanks Matthew and Charl for your responses.

I guess I have to dig deeper to find the root cause.

Thanks

Hi,

I have found the problem regarding our nexus proxy problem and if you upgrade your nexus you will face the same problem.

The source.sakaiproject.org responds with header value Server: openresty. If it changes to nginx the nginx scraper will match.

An alternative is to include /.meta/repository-metadata.xml so the nexus scraper match, but I guess you have to have a nexus-compatible repository then.

I have no idea how an older sonatype nexus scraper succeeds.

I've attached the debug log from our nexus.

Regards
Jonas

Hi,

Any comments on this problem?

Is it possible for you to replace the 'Server' header value 'openresty' with 'nginx' on the source.sakaiproject.org?
https://github.com/openresty/headers-more-nginx-module

You can easily verify the problem by running the latest nexus via docker: docker run -d -p 8081:8081 --name nexus sonatype/nexus:oss
https://hub.docker.com/r/sonatype/nexus/

Jonas

Hi,

Just a follow up on this issue.
One should not read the logs too carefully... the nexus proxy works ok, even if it complains about not being able to scrape the site.
I guess is does a direct GET with the calculated artifact path.

Jonas
