Issue seems to be because of deprecated configurations and renaming them in gradle7 - https://github.com/gradle/gradle/blob/c4d09af3db073776225e705307d93284df8753c0/subprojects/docs/src/docs/userguide/migration/upgrading_version_6.adoc#removal-of-compile-and-runtime-configurations

Would like to know if this was attempted already and was discouraged for any reason. Otherwise, happy to create a PR.
