maven-scm-plugin greater than 1.9.5 doesn't support scm:list command

[samirshaik]

This is not a issue with your extension code, but its in maven-scm-plugin that has an effect on your extension. I have tested with 1.9.5 and "mvn scm:list" command works as expected. But starting 1.10.0 and upto 1.11.2 the list command is not supported. Find below the stack trace for your reference.
