Gulp Watch JS infinite loop

Question

I’m Gulp’s new student, and I did this watch if my Java files are changed, it build-js. But when I run Gulp, it compiles all right but it keeps running the build-js an infinite loop. What I did wrong?

Thank you!

gulp.task('build-js', function (cb) {
            pump([
                gulp.src('lib/*.js'),
                uglify(),
                gulp.dest('dist')
            ],
                cb
            );
        });

gulp.task('watch-js', function () {
    gulp.watch('lib/*.js', ['build-js']);
})

gulp.task('default', ['build-js', 'watch-js']);

The problem may be because you are applying the watch in all the js, where it fires if any of them change. Try applying this way:

gulp.watch(['lib/*.js', '!lib/bundle.js'], ['build-js']);
