java - Maven Settings for multiple repositories

Question

I have the following in settings.xml

<mirrors>
       <mirror>
          <id>paid-jars</id>
          <name>jars with license</name>
          <url>http://url:8081/nexus/content/repositories/paidjars/</url>
          <mirrorOf>!central</mirrorOf>
      </mirror>
      <mirror>
          <id>Org-central</id>
          <name>mirror of central</name>
          <url>http://url:8081/nexus/content/repositories/central/</url>
          <mirrorOf>central</mirrorOf>
      </mirror>
  </mirrors>

In pom.xml I have two jars

1. apache-commons.jar (which I assumes to be downloaded from central)
2. licensed.jar (which I assume to be downloaded from paid-jars)

But when I run maven clean install it tries to download licensed.jar from Org-central.

How can I make it use paid-jars to download? Is it possible first it goes to Org-central and if fails it tries at paid-jars? If so, how? I don't want to put repo entries in pom.xml

Answer 1

you have to setup mirror

<mirror>
  <id>nexus</id>
  <mirrorOf>*</mirrorOf>
  <url>http://internal/nexus/content/repositories/thirdparty</url>
</mirror>

 <mirror>
  <id>google</id>
  <mirrorOf>google</mirrorOf>
  <url>http://google-maven-repository.googlecode.com/svn/repository</url>
</mirror>   

then add internal & external repo

<profile>
     <id>nexus</id>
  <repositories>

    <repository>
      <id>central</id>
      <name>central</name>
      <url>http://internal/nexus/content/repositories/thirdparty</url>
    </repository>


    <repository>
      <id>google</id>
      <name>google</name>
      <url>http://google-maven-repository.googlecode.com/svn/repository</url>
    </repository>

  </repositories>
</profile>
