I have a fairly standard use case for gulp-sourcemaps
https://github.com/floridoo/gulp-sourcemaps
gulp.src( bundle.src)
.pipe(sourcemaps.init())
.pipe(concat(bundle.dst + '.' + opts.ext))
.pipe(uglify())
.pipe(sourcemaps.write())
.pipe(gulp.dest('./public/built'));
This produces appropriately concatenated and uglyified files. However there are no source map additions to them. bundle.src
is an array of file paths. Not sure how to debug this.
