linux superuser use maven compile bower always fail

When I am root. Using 'mvn clean package -DskipTests=true' command always fail.

[INFO] — exec-maven-plugin:1.3.2:exec (Bower install) @ tez-ui —
bower ESUDO Cannot be run with sudo

Additional error details:
Since bower is a user command, there is no need to execute it with superuser permissions.
If you're having permission errors when using bower without sudo, please spend a few minutes learning more about how your system should work and make any necessary repairs.

You can however run a command with sudo using --allow-root option

I have to modify pom.xml.Why not modify pom.xml in future?
