[3.0-preview] Update polymer.json for webcomponentsjs changes.

[bicknellr]

The polyfill bundles have moved into /bundles.

So there's good news and bad news.

👍 The good news is that everyone that needs to sign a CLA (the pull request submitter and all commit authors) have done so. Everything is all good there.

😕 The bad news is that it appears that one or more commits were authored or co-authored by someone other than the pull request submitter. We need to confirm that all authors are ok with their commits being contributed to this project. Please have them confirm that here in the pull request.

Note to project maintainer: This is a terminal state, meaning the cla/google commit status will not change from this state. It's up to you to confirm consent of the commit author(s) and merge this pull request when appropriate.

[bicknellr]

(Expecting this to fail until those two PRs are in and the dependency on polymer-cli here is updated.)

[bicknellr]

This is not a blocker: these settings work as they are currently, they'll just become redundant in the future.

[bicknellr]

Actually, no, this needs to be updated to make sure that the builds include the new location of the webcomponentsjs bundles!

CLAs look good, thanks!

This works. We're a little lazy and just do this (which copies more than necessary): https://github.com/Polymer/pwa-starter-kit/blob/d52fd60/polymer.json#L9

I think with these we also fix it: webcomponents/webcomponentsjs#929

[bicknellr]

@abdonrd is that because polymer build includes things listed in files in your build output?

[abdonrd]

@bicknellr no, the idea is reduce the npm install @webcomponents/webcomponentsjs output.

You can see the actual output here:
https://unpkg.com/@webcomponents/webcomponentsjs@2.0.0-beta.2/

With webcomponents/webcomponentsjs#929 we reduce the output to only:

"bundles/**/*",
"entrypoints/**/*",
"custom-elements-es5-adapter.js",
"webcomponents-bundle.js",
"webcomponents-bundle.js.map",
"webcomponents-loader.js"

So the gulpfile.js will never exist in the project.

[bicknellr]

Oh, I read "I think with these we also fix it:" and though you were referring to this bug, rather than Keanu's comment about copying more than necessary.

[abdonrd]

@bicknellr ops! Sorry for the confusion! 😅
