indexing Kotlin repository fails when Gradle Java toolchains is enabled

When trying to index https://github.com/fwcd/kotlin-language-server, I get the following output:

Deprecated Gradle features were used in this build, making it incompatible with Gradle 8.0.

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