Hi,

There appear to be some errors in the debian package building process; I'd
like to double-check my approach for fixing them.

The wiki [1] gives the procedure for building debian packages as:
mvn install -P deps && dpkg-buildpackage

However, mvn install -P deps fails with:

[ERROR] Failed to execute goal on project cloud-deps: Could not resolve
dependencies for project
org.apache.cloudstack:cloud-deps:jar:4.1.0-SNAPSHOT: Could not find
artifact org.apache.cloudstack:cloud-awsapi:jar:4.1.0-SNAPSHOT in
apache.snapshots (http://repository.apache.org/snapshots) -> [Help 1]

The reason for this failure seems to be this section of deps/pom.xml:
    <dependency>
      <groupId>org.apache.cloudstack</groupId>
      <artifactId>cloud-awsapi</artifactId>
      <version>${project.version}</version>
    </dependency>

${project.version} is 4.1.0-SNAPSHOT, however looking at
https://repository.apache.org/content/groups/snapshots/org/apache/cloudstack/cloud-awsapi/,
I only see 4.0.0-SNAPSHOT.

If I replace ${project.version} for cloud-awsapi in deps/pom.xml with a
hardcoded "4.0.0-SNAPSHOT", mvn -P deps succeeds. An alternative fix would
be if 4.1.0-SNAPSHOT version of cloud-awsapi was available on
repository.apache.org.

I also found that in order for dpkg-buildpackage to succeed, I needed to
run "mvn install -P deps -pl deps" rather than just "mvn install -P deps".

For reference, if you run dpkg-buildpackages without running "mvn -P deps",
the error returned is:
/PATH/incubator-cloudstack/build/build-aws-api.xml:34: taskdef class
org.apache.axis2.tool.ant.AntCodegenTask cannot be found

Lastly, I would have expected "mvn clean" to remove the .jars in the deps
folder, however it does not - this made debugging "interesting"!

Proposed changes:
* Hardcode 4.0.0-SNAPSHOT as the version of cloud-awsapi in deps/poms.xml
* Change the wiki to reflect the fact that "mvn install -P deps -pl deps"
needs to be run when building debian packages
* Change mvn clean to remove the jars from the deps folder

Please let me know if those changes make sense, or if I'm missing
something. If they look OK, I'll create a patch and submit.

Thanks,
Dave.
