[Anthony Whyte]

Additional projects fixed:

Assignment2

Gradebook2 is not affected.

All Jenkins builds are back to normal, with the exception of roster2 which is sitting in the build queue.

Cheers,

>> Subject: [Building Sakai] SAK-21390: Maven 3 related pom changes breaks all Jenkins trunk builds/snapshot deployments
>> 
>> SAK-21390 introduced a change to the Maven <distributionManagement> repository <url> of purepoms and a couple of other indies (e.g., common, profile2) in order to support scp as a transport protocol, a protocol that now requires the associated wagon to be declared explictly as a build extension (it can also be declared as a dependency of the maven-deploy-plugin) [1].  For more details see Apache's Maven 3 compatibility notes [2].
>> 
>> This change has broken all other indie trunk builds/snapshot deployments despite the fact that builds are being performed by Jenkins using Maven 2.2.1.  Broken builds disrupt the refreshing of trunk snapshots.
>> 
>> The fix is actually a straightforward one and involves slimming the <dependencyManagement> element of all trunk indies, eliminating the entries for sakai-maven-snapshots-scp and sakai-maven2-scp as both elements are overriding the parent purepom entries unnecessarily.  The <build> extension need not be added as it's also inherited from purepoms [4].
>> 
>> I've fixed site and will jam through the other indie poms in order to stop Jenkins filling the inbox of affected developers (including myself) with failure notices of the following type:
>> 
>> [INFO] Error retrieving previous build number for artifact 'org.sakaiproject.polls:polls:pom': repository metadata for: 'snapshot org.sakaiproject.polls:polls:1.5-SNAPSHOT' could not be retrieved from repository: sakai-maven-snapshots-scp due to an error: Unsupported Protocol: 'scp': Cannot find wagon which supports the requested protocol: scp.
