Last night, PhoneGap Build was updated by Adobe:
The main purpose of the change was to add support for cli-9.0.0, which is required all new apps submitted to the Google Play Store after August 1, 2019. Existing apps have till November 1 to update.
The version of cli is set in Project Properties, in the PhoneGap section, under Version.
Here is what we have found in testing so far:
cli-6.1.0 is no longer supported
cli-6.5.0 is supported, but has errors for some projects
cli-8.0.0 is supported. Some projects work, some do not
cli-9.0.0 has problems
We’re looking at solutions now, and will keep you posted.
