I have a project that builds fine with maven with 1.9.24; upgrading the kotlin version to 2.0.0 gives me this, though:

[ERROR] Failed to execute goal org.jetbrains.kotlin:kotlin-maven-plugin:2.0.0:compile (compile) on project models: Compilation failure
[ERROR] java.lang.NoSuchMethodError: org.jetbrains.kotlin.fir.analysis.checkers.declaration.FirDeclarationChecker: method 'void <init>()' not found
[ERROR]         at org.jetbrains.kotlin.noarg.fir.FirNoArgDeclarationChecker.<init>(FirNoArgDeclarationChecker.kt:26)

This is with updating the kotlin-maven-plugin and the kotlin libraries to 2.0.0 across the board. Is this not what the upgrade is supposed to be, in simple form?

What are the next lines in the stacktrace?
That constructor got one argument added in 2.0.0, so something that calls that constructor is not compatible with 2.0.0.

haven't been able to replicate it - I'm reworking the build files altogether (mostly removing duplicated plugins down the hierarchy) and so far I've not re-encountered it. This may have been a broken-but-working-through-the-grace-of-God build somehow.

Ah, here we go, though:

Seems like you use an old version of the https://kotlinlang.org/docs/no-arg-plugin.html

ah ha! Okay, that's not VERY surprising. Working on it.
