Description
Is your feature request related to a problem? Please describe.
Gradle 8.2 deprecated conventions with nagging. They were deprecated for a long time, but without nagging.
https://docs.gradle.org/8.2-rc-2/userguide/upgrading_version_8.html#deprecated_access_to_conventions
Describe the solution you'd like
Migrate away from using conventions to extensions, so builds can pass nicely even with org.gradle.warning.mode=fail. At Gradle 9.0 this will become an error, so sooner or later the migration has to be done. Better do it sooner :)
Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
Additional context
The Project.getConvention() method has been deprecated. This is scheduled to be removed in Gradle 9.0. Consult the upgrading guide for further information: https://docs.gradle.org/8.2-rc-2/userguide/upgrading_version_8.html#deprecated_access_to_conventions
