Gradle failed to fetch dependencies?

After adding in Google AdMob to my project my game build was crashing when i tried to run it on my android. I tried to force resolve to fix it but when I try the bar just freezes and gives me this air.

Gradle failed to fetch dependencies.

Failed to run 'C:\Users\Lenovo\GameMaking\UnityStuff\UnityProjects\Flying & Dying\Temp\PlayServicesResolverGradle\gradlew.bat -b "C:\Users\Lenovo\GameMaking\UnityStuff\UnityProjects\Flying & Dying\Temp\PlayServicesResolverGradle\PlayServicesResolver.scripts.download_artifacts.gradle" --no-daemon "-PANDROID_HOME=C:/Users/Lenovo/AppData/Local/Android/Sdk" "-PTARGET_DIR=C:\Users\Lenovo\GameMaking\UnityStuff\UnityProjects\Flying & Dying\Assets\Plugins\Android" "-PMAVEN_REPOS=https://maven.google.com/" "-PPACKAGES_TO_COPY=com.google.android.gms:play-services-ads:15.0.1"' stdout:
