gradle reboot -- 2025W08 update

Good evening,

All hopes to get Gradle 8 to work with the FrankenKotlin are not lost 
yet.

After finishing to fix Gradle's build the first run of the new binaries 
was a pleasant surprise as it went straight into lauching its daemon 
process (I was expecting some fight there), and that one started 
built-in configuration tasks, compilation of the packaging's init.d 
Groovy scripts, and then crashed cleanly on compiler errors after 
attempting to compile the pluginManagement block of the root 
settings.gradle.kts.

It then took me several debugging sessions (debugging the bootstrap 
gradle as well to figure out the expected code path) to narrow down the 
issue to a missing step in function call resolution. In the process I 
adjusted the Kotlin compiler configuration in the Gradle DSL plugin and 
backported a few more minor fixes and features into Kotlin. But I had to 
give up on my last backport attempt as it appeared that it had a 
non-trivial dependency on a much larger change set: the Kotlin compiler 
plugin underwent a significant refactoring for release 1.3.50, and that 
includes some changes in the way the script compiler is configured.

For the record, despite requiring Kotlin 2.0.21 the current Gradle 8 
Kotlin DSL plugin is actually using the (legacy) K1 compiler, and this 
is among the reasons why I still think there are chances to get it to 
work with the FrankenKotlin.

I will now try to backport the whole scripting plugin from Kotlin 1.3.50 
into our FrankenKotlin and see how it goes, as this backport will bring 
its code state to something much closer to what it currently looks like 
in Kotlin 2.0.20. This is probably the last "large" Kotlin backport that 
I will attempt before declaring that approach to be a dead end.

Have a nice week-end,
