Question CommandInvokationFailure: Gradle build failed.

Good day everyone. I'm trying to connect ARCore in Unity, however whenever I try to build and run my program I keep getting an error at the gradle part and I couldn't find any solutions online to help me resolve my problem.

The error I get:

Code (CSharp):

1. CommandInvokationFailure: Gradle build failed.
