A minimal failing example for Closure Compiler issue #2559

Bar.js:1: ERROR - required "module$Baz" namespace not provided yet
import {
^^^^^^^^

1 error(s), 0 warning(s)

Notes

• Compilation works with v20170521.
• Error disappears if we replace lines 1-4 of Bar.js with import { Baz } from './Baz.js';. (js-beautify spreads the import over 4 lines.)
• I did not manage to reproduce the issue with only two modules.
