AR packaging problems

Hey guys, I’m an AR noob trying to get started with AR.
For a school assignment I’m trying to add a house in landscapes with AR.
However, when I try to package an empty level for an Android device I get the following error:

PackagingResults: Error: C:\WINDOWS\system32\cmd.exe failed with args /c “D:\Unreal projects\ARtest2\Intermediate/Android/APK\gradle\rungradle.bat” :app:assembleDebug

Does somebody know how to fix this?
