About Apache Maven scm plugin

Hi, we are trying to automate our release process. I am trying to use
Maven, it really simplifies many things. While using scm plugin's
prepare-release goal i have the following problem:
when i execute the command "maven scm:prepare-release" maven prompts
for a TAG_NAME (">What is the new tag name?"). is there a way to skip
this question? I have tried

maven scm:prepare-release -Dtag_name=test_release_1_0_1

but maven still asked me the tag name.

I would like to execute the command "maven scm:prepare-release" from a
bash script so i need a way to supply tag_name to scm:prepare-release
goal.

thanks...
