Configure local nexus server to download artifacts from other remote nexus repository

Question

I have installed Nexus repository locally and configuried maven to use my Nexus repo. I am trying to install broadleaf commerce but always getting the error. Broadleaf demo: https://github.com/BroadleafCommerce/DemoSite .

When I build the project with default maven settings file I can able to build the project. But with nexus local repo, I couldn't able to download the broadleaf artifacts. Can anyone help me what's wrong with my settings?

My settings.xml

<settings>
<mirrors>
<mirror>
  <!--This sends everything else to /public -->
  <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <url>http://localhost:8081/repository/maven-proxy-test/</url>
</mirror>
</mirrors>
<profiles>
<profile>
  <id>nexus</id>
  <!--Enable snapshots for the built in central repo to direct -->
  <!--all requests to nexus via the mirror -->
  <repositories>
    <repository>
      <id>central</id>
      <url>http://central</url>

    </pluginRepository>
  </pluginRepositories>
</profile>
 </profiles>
<activeProfiles>
<!--make the profile active all the time -->
<activeProfile>nexus</activeProfile>

When I build the broadleaf project I am always getting the build error.

Answer 1

You have 2 options and depends on how you want to handle it.

If your nexus should also hold the artifacts from broadleafcommerce you have to add it as a proxy repository:

In Nexus create a Proxy Repository with ID broadleafcommerce , URL http://nexus.broadleafcommerce.org/nexus/content/groups/public and Version policy Mixed In your settings.xml define your mirrors:

<mirrors>
    <mirror>
      <id>nexus</id>
      <mirrorOf>*,!broadleaf-repo</mirrorOf>
      <url>http://localhost:8081/repository/maven-proxy-test/</url>
    </mirror>
    <mirror>
      <id>broadleafcommerce</id>
      <mirrorOf>broadleaf-repo</mirrorOf>
      <url>http://nexus.broadleafcommerce.org/nexus/content/groups/public/</url>
    </mirror>
</mirrors>

If you do not want to have the artifacts from broadleafcommerce in your nexus repository:

Define your mirror in that way:

<mirrors>
    <mirror>
      <id>nexus-group</id>
      <mirrorOf>*,!broadleaf-repo</mirrorOf>
      <url>http://localhost:8081/repository/maven-proxy-test/</url>
    </mirror>
</mirrors>

Notice that <mirrorOf>*,!broadleaf-repo</mirrorOf> points to the ID of your defined repository and excludes it.
