Как правильно прописать исключения в gulp?

var path = {
    build: {
        html: 'assets/build/',
        js: 'assets/build/js/',
        css: 'assets/build/css/',
        img: 'assets/build/img/',
        fonts: 'assets/build/fonts/'
    },
    src: {
        html: 'assets/src/*.html',
        js: 'assets/src/js/main.js',
        style: 'assets/src/style/*.scss', '!assets/src/style/my.scss', '!assets/src/style/variables.scss',
        img: 'assets/src/img/**/*.*',
        fonts: 'assets/src/fonts/**/*.*'
    },
    watch: {
        html: 'assets/src/**/*.html',
        js: 'assets/src/js/**/*.js',
        css: 'assets/src/style/**/*.scss',
        img: 'assets/src/img/**/*.*',
        fonts: 'assets/srs/fonts/**/*.*'
    },
    clean: './assets/build/*'
};
