Hello, when I run my build, I see some warn messages like

[warn] �[33m▲ �[43;33m[�[43;30mWARNING�[43;33m]�[0m �[1mDuplicate key "abc" in object literal�[0m [duplicate-object-key]

I would like my build to error out and not be successful if there are any warnings like that. Is there some sort of strict mode option that allows me to do so?
