tools: Polymer build fails silently with "bundle": true in polymer.json

Description

Polymer does not build if the option “bundle” : true is specified in polymer.json

Unbundled builds remain OK. But bundled builds fail silently (ex: “bundle”: true or “preset”: “es6-bundled”)

Versions & Environment

• Operating System: Win 7 x64 (Windows seven 64 bits)

C:\Program Files\nodejs\otority>node --version
v8.1.2

C:\Program Files\nodejs\otority>npm --version
5.0.3

C:\Program Files\nodejs\otority>polymer --version
1.3.1

Steps to Reproduce

A simple polymer.json with “bundle”: true in the build section

{
  "name": "Otority",
  "entrypoint": "public/index.html",
  "shell": "public/src/my-app/my-app.html",
  "fragments": [
    "public/src/my-contact-list/my-contact-list.html",
    "public/src/my-contact-get/my-contact-get.html",
    "public/src/my-contact-set/my-contact-set.html",
    "public/src/my-tractage/my-tractage.html",
    "public/src/my-collage/my-collage.html"
  ],
  "sources": [
    "public/**/*",
    "public/fonts/**/*",
    "public/js/**/*",
    "public/images/**/*",
    "bower.json"
  ],
  "extraDependencies": [
  	"public/manifest.json",
  	"public/firebase-messaging-sw.js",
  	"public/bower_components/webcomponentsjs/webcomponents-lite.js"
  ],
  "lint": {
    "rules": ["polymer-2-hybrid"],
    "ignoreWarnings": []
  },
  "builds": [
    {
      "name": "bundled",
      "bundle": true
    }
  ]
}

Expected Results

C:\Program Files\nodejs\otority>polymer build
info:    Clearing build\ directory...
info:    (bundled) Building...

C:\Program Files\nodejs\otority>

=> A bundled version is created

Actual Results

C:\Program Files\nodejs\otority>polymer build
info:    Clearing build\ directory...

C:\Program Files\nodejs\otority>

=> no bundled version created

You might observe that actual results do not show the line : “info: (bundled) Building…”, meaning something goes wrong.
