tag in pom - not recognising accurev -

Hi

Im trying to use <scm> maven tag to obtain the code from an accurev branch;

Following Maven's instruction (http://maven.apache.org/scm/maven-scm-providers/maven-scm-provider-accurev/) if I follow this pattern 

my SCM tag in POM looks like this:

    <scm>

            <connection>scm:accurev:jenkins/jenkins@longscm01d:5050:/schema</connection>

            <developerConnection>scm:accurev:jenkins/jenkins@longscm01d:5050:/schema</developerConnection>

            <!-- <url>http://scm.gta.travel.lcl/viewvc/projects/JCBS/?root=GTA-Projects</url> -->

    </scm>

However the build doesnt seems to understand the pattern and console log says the following:

[INFO] [release:prepare {execution: default-cli}]

[INFO] Resuming release from phase 'scm-check-modifications'

[INFO] Verifying that there are no local modifications...
