Answer 1

I figured out the answer:

To remove readonly attribute of all files under a directory recursively, we run the following command in windows Command line

attrib -r <dir-name>\*.* /s

Following gulp task removes readonly attribute of all files under

gulp.task('remove-readonly-attributes', function() {
    require("child_process").exec("attrib -r <dir-name>\*.* /s");
});
