I saw this error multiple times, but I didn't see in the docs we should use

on

, it said

true

. Is this a typo?

org.gradle.unsafe.configuration-cache=true

https://docs.gradle.org/6.6/userguide/configuration_cache.html

Option configuration-cache doesn't accept value 'true'. Possible values are [OFF, ON, WARN]

probably open an issue, looks like https://github.com/gradle/gradle/commit/1c882367e8f1db5fc323ccf5d9e673f4a0ad2dab didn't update docs

What version of Gradle are you using?

Yeah, I updated the wrapper but I didn't update the system gradle version to 6.6

What do you mean by system gradle version?

i assume he means the version of gradle he has actually installed and on the PATH - the one that would execute if he typed

gradle build

instead of

./gradlew build

I would recommend always using the wrapper to avoid inconsistencies between the configuration of the project and the gradle version.
