[Incubating] Problems report is available at: file:///home/funpro/datasea/src/processing4/.build/reports/problems/problems-report.html

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/8.11/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

Feel free to close the issue if you prefer to keep your build.gradle.kts as pure and beautiful as you have it now :-)

ps. I suggest not updating to Gradle 9.0.0 until things settle down in a few weeks or months.
