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

This is the solution:

cordova plugin rm cordova-plugin-compat --force

Answer 2

Going to add my 2 cents since none of the solutions work for me. Only thing that worked for me:

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

Answer 3

One solution: downgrade cordova android platform @6.2.3

$ cordova platform remove android && cordova platform add android@6.2.3

Answer 4

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.

Answer 5

I'am using for Ionic 3 Project, I have to do:

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

it's work for me.

Answer 6

With my Ionic 3 project it was enough to run:

ionic cordova plugin rm cordova-plugin-compat --force
ionic cordova plugin add cordova-plugin-compat@1.2

And then run a build again. No need to remove and add the platform.
