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

There may be mismatch of the plugins in the android builds. So better run 2 commands for successful build

cordova platform rm android
cordova platform add android

After wasted 2 days this seems to be only working solutions for me.
