An app's production build breaks if source maps are enabled.

When I run ember build -e=production on an app that has ember-esri-loader installed, I get the following error:

Error: ENOENT: no such file or directory, open 'project-path/esri-loader-test/tmp/uglify_writer-input_base_path-GKD3EADg.tmp/assets/dist/esri-loader.min.js.map'

Thought it might have something to do with this issue: emberjs/ember.js#15720, but I updated to my app to ember v2.16.0 but still get the error.

Here's a sample app: https://github.com/ssylvia/ember-esri-loader-sourcemap-build-fail-demo.

Thanks @ssylvia

Did you already try excluding esri-loader from minification in that app?

[tomwayson]

I was able to repro in the dummy app by copying the source map config from your app:

    sourcemaps: {
      enabled: true,
      extensions: ['js'],
    },

I was then able to fix the build error by excluding esri-loader from minification with:

    minifyJS: {
      options: {
        exclude: ["**/esri-loader.min.js"]
      }
    }

That's at least a workaround for now.

@ssylvia FYI - I have fixed this issue in esri-loader@1.5.2, but there are still some sourcemap issues in ember-esri-loader, so I won't be cutting a new release of this repo until I've had time to work those out. In the mean time you can bump esri-loader.

@ssylvia this is resolved in v0.2.3

Thanks @tomwayson!
