我有同样的问题，几乎相同的设置。您是否尝试将cordova-plugin-facebook4恢复到版本1.7.4？
对我来说，这不是一个解决方法，但现在是一种解决方法，只是为了让应用程序建立。
如果还原插件修复它，也可以看看https://github.com/phonegap/phonegap-plugin-barcodescanner/issues/535。

进入平台 - > Android的 - >的build.gradle
defaultConfig下添加multiDexEnabled true这样
defaultConfig {
multiDexEnabled true
}
这个工作对我..

'多DEX文件定义Lcom/google/zxing/BarcodeFormat' - 这表示Google条码库的多个定义，很可能是由科尔多瓦插件。请发布项目中使用的插件列表（'cordova plugin ls'） – DaveAlden
