Fast Invoker Plugin Configuration

  If you follow the recommended approach and use a dedicated local repository for the integration tests (e.g.
  <<<target/local-repo>>>), you will likely encounter long build times. If the test repository has been cleaned, the
  plugin needs to re-download all artifacts from the central repo and the resulting network traffic slows the test
  execution down.

  But you can configure the plugin to download released artifacts from your local repo.
  <Note:> This will work without optional settings with Maven >= 2.0.9 because many plugins 
  versions are locked in the super POM. For older versions, you have to lock plugins versions.
  
  To enable this feature, you have to add a <<<settings.xml>>> file in your project (for example in <<<src/it/settings.xml>>>)
  and modify the plugin configuration as this :  
  
-------------------
<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-invoker-plugin</artifactId>
        <version>1.2</version>
        <configuration>
          ...
          <settingsFile>src/it/settings.xml</settingsFile>
          ...              
        </configuration>
      </plugin>
    </plugins>
  </build>
  ...
</project>
-------------------

  The settings must contains the following content :
  
-------------------
<?xml version="1.0"?>
<settings>
  <profiles>
    <profile>
      <id>it-repo</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>      
      <repositories>
        <repository>
          <id>local.central</id>
          <url>file://@localRepository@</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>             
        </repository>        
      </repositories>
      <pluginRepositories>
        <pluginRepository>
          <id>local.central</id>
          <url>file://@localRepository@</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>          
        </pluginRepository>
      </pluginRepositories>
    </profile>
  </profiles>
</settings>
