Command failed with exit code 1 Error output:

• What went wrong:
  Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
  > com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives:

I download both plugin using these command:

ionic cordova plugin add phonegap-plugin-barcodescanner
npm install @ionic-native/barcode-scanner

ionic cordova plugin add cordova-plugin-facebook4 --variable APP_ID="app_id" --variable APP_NAME="app_name"
npm install --save @ionic-native/facebook

En mi caso descubrimos junto a un amigo que el conflicto lo genera un plugin, seguramente tienen mas de un plugin instalado. en mi caso era que tenia este npm uninstall cordova-plugin-facebook4 que no lo estaba usando...

@Mitnick21 yes I've just found the same problem. it's conflict with cordova-plugin-facebook4.
I tried to solve it for 3 days but it seems impossible.

Hi,
I've just found the same problem. I found a plugin that works well with phonegap-plugin-barcodescanner. This is: cordova-plugin-facebook4-no-zxing
I hope it helps.
