Look up hostname from Maven

Use a groovy script to set the project property

    <plugin>
        <groupId>org.codehaus.groovy.maven</groupId>
        <artifactId>gmaven-plugin</artifactId>
        <executions>
            <execution>
                <phase>generate-resources</phase>
                <goals>
                    <goal>execute</goal>
              </goals>
               <configuration>
                  <source>
                  project.properties["hostname"] = InetAddress.getLocalHost().getHostName()
                 </source>
             </configuration>
         </execution>
      </executions>
 </plugin>

${env.COMPUTERNAME} works for me..
