Maven not pulling dependency from correct repository

I have 3 repositories setup in our Nexus Repository manager

COMPANY_maven-proxy -> proxies https://repo1.maven.org/maven2/
COMPANY_maven-redhat-proxy -> proxies https://maven.repository.redhat.com/ga/
3rd-Party-Tools -> our companies homegrown 3rdParty dependencies

When I run the mvn install command it pulls everything I'm looking for from each of these repositories (the dependency itself and the transitive dependencies). All except for one!

org.jboss.seam.integration:jboss-seam-int-jbossas:pom:7.0.0.GA

This dependency lives in the Redhat maven repository:

<dependency>
   <groupId>org.jboss.seam.integration</groupId>
   <artifactId>jboss-seam-int-jbossas</artifactId>
   <version>7.0.0.GA</version>
   <type>pom</type>
</dependency>

For whatever reason, this one dependency is looking under the COMPANY_maven-proxy repository instead of the COMPANY_maven-redhat-proxy repository.

Here's what I have for my settings.xml:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
    <mirrors>
    <mirror>
      <!--This sends everything to COMPANY_maven-proxy that isn't in COMPANY_maven-redhat-proxy -->
      <id>COMPANY_maven-proxy</id>
      <url>http://FQDN:8081/nexus/repository/COMPANY_maven-proxy/</url>
      <mirrorOf>*,!COMPANY_maven-redhat-proxy</mirrorOf>
    </mirror>
    <mirror>
      <!-- This sends everything to COMPANY_maven-redhat-proxy that isn't in COMPANY_maven-proxy -->
      <id>COMPANY_maven-redhat-proxy</id>
      <url>http://FQDN:8081/nexus/repository/COMPANY_maven-redhat-proxy/</url>
      <mirrorOf>*,!COMPANY_maven-proxy</mirrorOf>
    </mirror>
    <mirror>
      <!--This sends everything else to 3rd-Party-Tools -->
      <id>3rd-Party-Tools</id>
      <url>http://FQDN:8081/nexus/repository/3rd-Party-Tools/</url>
      <mirrorOf>!COMPANY_maven-proxy,!COMPANY_maven-redhat-proxy</mirrorOf>
    </mirror>
  </mirrors>
</settings>

Here's the error I get:

Failed to collect dependencies at org.jboss.seam.integration:jboss-seam-int- 
jbossas:pom:7.0.0.GA: Failed to read artifact descriptor for org.jboss.seam.integration:jboss- 
seam-int-jbossas:pom:7.0.0.GA: Could not find artifact org.jboss.seam.integration:jboss-seam- 
int:pom:7.0.0.GA in COMPANY_maven-proxy (http://FQDN:8081/nexus/repository/COMPANY_maven-proxy/) -> [Help 1]

I've tried multiple combination's within the <mirrorOf> tag but nothing has worked. I've even put this transitive depency in my pom under <dependencies> and/or <dependencyManagement>.

Any help on this would be appreciated!

Thanks!

The mirrors are for already existing repositories declared. In your settings.xml you do not have repositories listed, but the default Maven Central. Thus it makes sense to define just a mirror of Maven Central, redirecting to the company's Nexus repo. with a rare trick, one could register a mirror for any external repos, for example:

    <mirror>
      <id>public</id>
      <mirrorOf>central</mirrorOf>
      <name>Let the default Maven Central repository is resolved in the local Nexus' public repository</name>
      <url>http://FQDN:8081/nexus/repository/COMPANY_maven-proxy/</url>
    </mirror>

Any mirror from your example should be registered in the pom.xml as repositories.

Edited:

  • removed the second ("other") mirror, as the example was adapted from a case where the repository manager to direct to runs at localhost.
