Answer 1

The issue was with my rootProject.name definition in settings.gradle

I had to change

rootProject.name='Cordova Alternative Pattern'

to

rootProject.name='CordovaAlternativePattern'

Answer 2

The same error occurs if you use any 'illegal' non-English characters in rootProject.name. To resolve this, change it to English letters without spaces or other special characters.

And yes, it may be necessary to report this issue to JB, at the very least by enabling proper logging.
