When I using maven-git-commit-id-plugin,I want use ${git.commit.id.abbrev} in my pom.xml.
The code is looks like thie:

The name of war is "xxx-0.0.1-${git.commit.id.abbrev}-20151126222413.war".
You can see,the value of ${git.commit.id.abbrev} is not replaced.
But it had been replaced in the "git.properties".

I don't know why and I tried to many ways,also asked google,but I'm faild.
Can anyone help me?
Thanks.
