Publishing a build scan to scans.gradle.com requires accepting the Gradle Terms of Service defined at https://gradle.com/terms-of-service. Do you accept these terms? [yes, no] 

[Discut]

I saw some questions on Stack Overflow about it. Maybe it's related to the JDK version?

[gotson]

You need to use Java 17 to call Gradle.

It can work, thanks.
