Ionic Push not working, build failed

hello All,
I’m using Ionic Push plugin in one of my app and getting this error when running ionic cordova build android command.
Please find the Screenshot.

Anyone can help me out?

It seems the dex version is causing the error.
You can build but by removing the platforms and plugin folder from your app. I know that’s not a solution but you can do that for checking purpose.
I think the some plugin is creating some issue.
Back up your project in another folder then try deleting the platform folder and plugin folder after that re-add the platforms then you can build.
You can follow this:
