[Polymer - build]: problem with minification

[xkotj]

Hello, I've been developing plugins for one system.

Project uses: "dependencies": { "@polymer/iron-icon": "^3.0.1", "@polymer/iron-icons": "^3.0.1", "@polymer/iron-pages": "^3.0.1", "@polymer/paper-tabs": "^3.1.0", "@vaadin/vaadin-button": "^2.2.0", "@vaadin/vaadin-checkbox": "^2.2.8", "@vaadin/vaadin-custom-field": "^1.0.1", "@vaadin/vaadin-date-picker": "^3.3.4", "@vaadin/vaadin-form-layout": "^2.1.2", "@vaadin/vaadin-grid": "^5.4.2", "@vaadin/vaadin-icons": "^4.3.1", "@vaadin/vaadin-notification": "^1.4.0", "@vaadin/vaadin-ordered-layout": "^1.1.0", "@vaadin/vaadin-progress-bar": "^1.1.0", "@vaadin/vaadin-radio-button": "^1.2.0", "@vaadin/vaadin-select": "^2.1.1", "@vaadin/vaadin-tabs": "^2.1.1", "@vaadin/vaadin-text-field": "^2.4.3", "@vaadin/vaadin-time-picker": "^1.2.2", "@webcomponents/webcomponentsjs": "^2.2.10", "lit-element": "^2.1.0", "pwa-helpers": "^0.9.1", "redux": "^4.0.1", "redux-thunk": "^2.3.0" }

I used polymer-cli for bundling and minifying polymer build --js-minify --js-compile --js-transform-modules-to-amd --css-minify --html-minify --bundle

Last functional bundle was with version polymer-cli 1.9.6

New versions (1.9.7 - 9) seems to corrupt bundled file. When I look at network activity I see that index.html is not minified in new versions

When I deploy plugin to the system I can see only this: App name ``iron-listmust be given a

My question is what is the main difference between those versions? I looked at changelog and first change was treeshaking. What else coulde be doing this?

Thanks for any hints.

I have the same issue but with a completely different setup etc. Does not minify correctly. I was using polymer-cli 1.9.10. Moved to version 1.9.6 and it now works correctly.
