You are asking on the phonegap forum, but it seems a phonegap build question, the right phonegap build forum is https://forums.adobe.com/community/phonegap/build
That answer seems old, you should use cordova-plugin-inappbrowser to open external links in the phone browser
Install it adding this line to the config.xml
and open the phone browser with
"cordova-plugin-inappbrowser" is no longer supported. Do you know what has replaced it?
cordova-plugin-inappbrowser is an official plugin and it's still supported, why do you say it's not supported?
PhoneGap rejected my build on the grounds that this had been discontinued some time in November this year. However if you add source="npm" then they are happy.
What is no longer supported is pgb source, you should use npm as source in all your plugins
