Could not find artifact in NexusRepository (Using Maven Proxy repository)

Question

We are behind corp proxy. I have installed Sonatype Nexus repository manager.

Tried to setup npm and maven proxy repositories following this link Maven and NPM Proxy repositories . NPM proxy setup worked well and test projects passed. But getting issues with Maven proxy setup.Created a test project which is using maven and it is running into issues.The dependencies are not being downloaded.

Things I did
1) Setup HTTP and HTTPS Proxy in Nexus ( since we are behind Corp proxy)

2) Created a Maven proxy and Maven Hosted repository and grouped them via Maven-public repository named maven-public.

3) Created ~/.m2/settings.xml with below contents

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      https://maven.apache.org/xsd/settings-1.0.0.xsd">
   <mirrors>
    <mirror>
     <id>NexusRepository</id>
     <url>http://nexusrepohost:8080/repository/maven-public/</url>
     <mirrorOf>*</mirrorOf>
    </mirror>
   </mirrors>
   <proxies>
    <proxy>
      <id>http</id>
      <active>true</active>
      <protocol>http</protocol>
      <host>proxyserver</host>
      <port>8080</port>
      <username>proxyusername</username>
      <password>proxypassword</password>
      <nonProxyHosts>|127.0.0.1|nexusrepohost</nonProxyHosts>
    </proxy>
    <proxy>
      <id>https</id>
      <active>true</active>
      <protocol>https</protocol>
      <host>proxyserver</host>
      <port>8080</port>
      <username>proxyusername</username>
      <password>proxypassword</password>
      <nonProxyHosts>|127.0.0.1|nexusrepohost</nonProxyHosts>
    </proxy>
  </proxies>
</settings>

The Error message is

NOTE:

1) Definitely not a proxy issue,because npm tet worked fine and it downloaded artifacts from NPM registry. I can see them in Nexus.

Any setting I am missing?

What happens if you go to http://nexusrepohost:8080/repository/maven-public/ in a web browser (or curl, netcat, etc.) — Catchwa, Oct 03 '19 at 04:24
curl andbrowser gives me this message "This maven2 group repository is not directly browseable at this URL." — VVP, Oct 03 '19 at 04:40
I'd try mvn with the -X parameter to get debug logging. Also, you've got a HTTP and HTTPS proxy defined but only seem to be using HTTP? — Catchwa, Oct 03 '19 at 04:43
The log in original post is from a mvn -X execution. Not sure about why http is only used. Nexus allows us to set both https and http proxy. Same is set in maven settings.So possible that choosing http / https is done by maven ? — VVP, Oct 03 '19 at 05:20
That nonProxyHosts value looks wrong, there shouldn't be a leading '|': https://maven.apache.org/guides/mini/guide-proxies.html — rseddon, Oct 03 '19 at 19:23
@rseddon You are right. It was a typo while copying the contents to this forum. Settings.xml is good. Still the issue exists. — VVP, Oct 10 '19 at 03:25
