Multiple dex files define Lorg/apache/cordova/BuildHelper

Question

I\'m in trouble since yesterday. In my internship I faced the following build error, but I couldn\'t understand why :

$ cordova build android

[...]

FAILURE         


        

Answer 1

I had to do:

cordova plugin rm cordova-plugin-compat --force
cordova plugin add cordova-plugin-compat@1.2
cordova platform rm android
cordova platform add android@6.3.0

considering you can't simply remove cordova-plugin-compat because plugins like cordova-plugin-file depend on it.
