issue with build map

[jbanety]

Sometimes when I run the command jspm build $(jspm trace --deps ./app.js) -h -o, the output map is wrong.

Example of output :

{
  "imports": {
    "@etdsolutions/stacks": "./dist/stacks-ff183556.js",
    "@erp/ui-components/parcels/list.parcel.js": "./dist/request-db1f16d4.js",
    "@etdsolutions/request": "./dist/routie-ad357c93.js",
    "@etdsolutions/uid": "./dist/list.parcel-8b402777.js",
    "@erp/ui-components/parcels/sidenav.parcel.js": "./dist/uid-0b9cbb9d.js",
    "@etdsolutions/routie": "./dist/sidenav.parcel-466e49de.js"
  }
}

As we can see, the rollup generated code is not corresponding to the good bare specifier.
After investigating, it seems that jspm's inputObj and rollup's output are not is the same order but I can't understand wky.

Any idea ?

Very interesting. This sounds like a Rolllup bug then as the sort is supposed to be stable.

Rollup does its output sort here - https://github.com/rollup/rollup/blob/master/src/rollup/index.ts#L359.

I guess the problem then is the outputBundle object not being populated in entry point order first.

Definitely an important bug to fix.

Alternatively I wonder if we could do some sort of matching in jspm to correct for this.

I create a PR #2470 to fix this issue.
