Andrei,

I modified the pom file as follows:

          </excludes>
        </configuration>
      </plugin>
    </plugins>
  </build>
</project>

The problem is still there.
I installed whirr 0.9.0-SNAPSHOT on my desktop and check /home/meng/whirr/cli/target/lib, the guava version is guava-14.0.1.jar
then I went to /home/meng/cloudstack/api/target/dependency, the guava version there is guava-14.0-rc1.jar
It looks true that cloud-api requires a specific version of Guava. Do you know how I can solve this situation? The cloudstack api pom file does not include guava as an explicit dependency. 

I have a class now, I will come back at 3.

Thanks again Andrei!

Best Regards,
Meng

Do not add jclouds as an explicit dependency - maven will find the right 
one as a transitive dependency of Whirr. That will solve your problem
unless cloud-api requires a specific (older) version of Guava.

 Hi all,


I am adding a plugin to CloudStack. One of the APIs of this plugin
(launchCluster) is to start a haoop cluster on Cloudstack using Whirr. I 
included whirr as a dependency to my plugin.

<dependency>
      <groupId>org.apache.whirr</****groupId>

      <artifactId>whirr</artifactId>
      <version>0.8.2</version>
      <type>pom</type>
</dependency>
When I test this api in CloudMonkey I am getting the following error: 

 launchCluster config=/home/meng/whirr/dream

The execute method for the lauchClusterCmd is below:

 public void execute()  {
LaunchClusterResponse response = new LaunchClusterResponse(); 
        response.setObjectName("****launchCluster");

        LaunchClusterCommand command = null;
        try {
            command = new LaunchClusterCommand();  //imported from
 org.apache.whirr.cli.command.****LaunchClusterCommand;
        } catch (Exception ex) {
            Logger.getLogger(****LaunchClusterCmd.class.****
getName()).log(Level.SEVERE,

null, ex);
        }
        String[] args = new String[2];
        args[0] = "--config";
        args[1] = config;

        try {
            command.run(System.in, System.out, System.err,
Arrays.asList(args));
        } catch (Exception ex) {
            Logger.getLogger(****LaunchClusterCmd.class.****
getName()).log(Level.SEVERE,
null, ex);
        }
         response.setResponseName(****getCommandName());

         output = "successfully launched the cluster.";
         response.setOutPut(output);
         this.setResponseObject(****response);

    }
Does the above error indicate that I am missing a couple of class files 
or am I not configuring the JAVA classpath correctly?

Also could someone explain what does this file
client/target/conf/classpath.****conf do ?


Thanks.

Cheers,
Meng
