Deprecated Gradle features were used in this build, making it incompatible with 
Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings 
and determine if they come from your own scripts or plugins.

For more on this, please refer to 
https://docs.gradle.org/8.10/userguide/command_line_interface.html#sec:command_line_warnings
 in the Gradle documentation.
