Unable to minify scripts

[James-ZHANG]

For some reason, usemin fails to output any minified js files and the output html contains no script tag as well. It works for css minification, however... I've followed the doc and checked my gulpfile.js quite a few times and it shouldn't contain any trivial errors. Below is my block in html:

<!-- build:js scripts/main.js -->
    <script src="../bower_components/angular/angular.min.js">
    </script>
    <script src="scripts/app.js">
    </script>
<!-- endbuild -->

, and my gulp task:

gulp.task('usemin', ['jshint'], function() {
    return gulp.src('./app/menu.html')
        .pipe(usemin({
                    css: [minifycss(), rev()],
                    js: [uglify(), rev()]
        }))
        .pipe(gulp.dest('dist/'));
});

what's your jshint task? this ?

gulp.task('jshint', function() { return gulp.src('app/scripts/**/*.js') .pipe(jshint()) .pipe(jshint.reporter(stylish)); });

or can you just paste the whole gulpfile.js
