Sourcemaps with Uglify, Ng-Annotate, and Concat: Not pointing to the right location or file!

[gwetch]

Using Gulp. I have been working on getting a sourcemap to work properly for debugging purposes in development without much luck. Any tips would be much appreciated, I have spent many hours rearranging and organizing my code yet nothing will help it. It will point to the end of the code on the last file in the list instead of showing where the actual issue is.

var gulp = require('gulp'),
    sass = require('gulp-sass'),
    prefix = require('gulp-autoprefixer'),
    concat = require('gulp-concat'),
    jshint = require('gulp-jshint'),
    del = require('del'),
    nodemon = require('gulp-nodemon'),
    sourcemaps = require('gulp-sourcemaps'),
    uglify = require('gulp-uglify'),
    ngAnnotate = require('gulp-ng-annotate')

gulp.task('js', function(){
    return gulp.src('./assets/js/**/*.js')
    .pipe(jshint('.jshintrc'))
    .pipe(jshint.reporter('default'))
    .pipe(sourcemaps.init({identityMap: true}))
    .pipe(ngAnnotate())
    .pipe(concat('scripts.js'))
    .pipe(uglify())
    .pipe(sourcemaps.write('./', {sourceMappingURLPrefix: './maps/js', includeContent: false, sourceRoot: './assets/js/**/*.js'}))
    .pipe(gulp.dest('./views/dist/js'))
})
