I use FrameMaker to create Mobile App and now I cannot due to plugin issue. The PhoneGap Build Public Plugin Repository Shut Down but FM is still adding plugins when creating APK. Looks like FrameMaker team has not updated their software to change/remove use of these plugins.
<gap:plugin name="com.indigoway.cordova.whitelist.whitelistplugin" source="pgb" spec="1.1.1"/>
FM version 126.96.36.1997
You can change the config.xml yourself to point to npm, but otherwise you'll need to wait for them to update their support for PhoneGap Build.
