Maven SCM tag

[Nandita LN (nln)]

Hi,

I am using  Maven SCM with perforce. I need to specify the specific 
revision/changelist number to be used for SCM analysis.
Please let me know how to configure in POM.xml.Here is my current configuration 
,but not working as expected:
<scm>
                                
<connection>scm:perforce:username@server:2667://depot</connection>
                                
<developerConnection>scm:perforce:username@server:2667://depot</developerConnection>
                                
<url>scm:perforce:username@server:2667://depot</url>
                                <tag>559513</tag>
                </scm>
Thanks,
Nandita
