main.js etc missing in ionic 3 /www/build

I'm submitting a ... (check one with "x")
[x] bug report
[ ] feature request

Current behavior:
After installing cordova-plugin-market in ionic 3 and building, the /www/build folder only contains two files. The following files are missing: main.css, main.css.map, main.js, main.js.map

When running the app with 'ionic run android -lsc --device' this results in 404 errors when the app is run.

Expected behavior:
Correct files in /www/build

Steps to reproduce:
After I install cordova-plugin-market running the app via 'ionic run android -lsc --device' succeeds but the build folder only contains two files so the app fails with several 404 errors. The build output concludes with the following. There are no errors in the rest of the build output:

LAUNCH SUCCESS

The build folder is virtually empty

/www/build
    polyfills.js
    sw-toolbox.js

If I remove cordova-plugin-market and re-run, the /www/build looks correct:

/www/build
    main.css
    main.css.map
    main.js
    main.js.map
    polyfills.js
    sw-toolbox.js
