我根据互联网搜索结果尝试过的事情：
cordova clean + cordova build 所以同样的错误不断发生。
这是我的package.json文件供参考：

可能冲突的插件（来自我的package.json）
一些答案说明了管理Android / firebase版本的插件冲突。那么也许使用所有这些库/插件可能是问题所在？
npm
cordova插件
我还能尝试解决什么？在这个问题上已经花了2天了：（
答案 0 :(得分：1)
您可以尝试执行此步骤
cd platforms/android
gradlew clean
cd ..
cd ..
ionic cordova build android --prod --release
