After migrating to ktlint 1.2.1 I am getting an error when attempting to suppress _property_naming_ in the following file:

ExternalModel.kt

@Suppress("ktlint:standard:property-naming")
interface ExternalModel {
    val sys_id: String?
    val table_name: String
}

$ ./gradlew ktlintFormat
...
* What went wrong:
Execution failed for task ':runKtlintCheckOverMainSourceSet'.
> A failure occurred while executing org.jlleitschuh.gradle.ktlint.worker.KtLintWorkAction
   > 'void org.jetbrains.kotlin.psi.psiUtil.PsiUtilsKt.checkDecompiledText(org.jetbrains.kotlin.com.intellij.psi.PsiElement)'

I am using the following configuration:

Gradle 8.6
Amazon Corretto 17.0.10-amzn
Ktlint Gradle 12.1.0
ktlint 1.2.1

Anyone come across this?

It appears to have broken after 1.0.1

As a workaround, replaced with:

@Suppress("PropertyName")
interface ExternalModel {
    val sys_id: String?
    val table_name: String
}

I quickly tried to reproduce with Ktlint CLI, but I do not get an error. Please raise an issue and include your .editorconfig when you can reproduce it with the CLI version.

Issue is not reproducible via CLI as it is likely a fat-binary with all dependencies baked in?

I re-ran Gradle with stacktraces enabled and this is what I found:

Caused by: java.lang.NoSuchMethodError: 'void org.jetbrains.kotlin.psi.psiUtil.PsiUtilsKt.checkDecompiledText(org.jetbrains.kotlin.com.intellij.psi.PsiElement)'

The missing method, which ktlint engine is unable to find, is PsiElement.checkDecompiledText. Looking at the Kotlin sources repository, said method was not introduced until version 1.9.20:
• https://github.com/JetBrains/kotlin/blob/v1.9.10/compiler/psi/src/org/jetbrains/kotlin/psi/psiUtil/psiUtils.kt (missing)
• https://github.com/JetBrains/kotlin/blob/v1.9.20/compiler/psi/src/org/jetbrains/kotlin/psi/psiUtil/psiUtils.kt (#e9c8be3)
I tested upgrading my project to Kotlin language version 1.9.20 (from 1.9.10) and Gradle task ktlintFormat does not fail anymore.

CLI is indeed a fat binary including the embedded kotlin compiler.

The missing method, which ktlint engine is unable to find, is PsiElement.checkDecompiledText. Looking at the Kotlin sources repository, said method was not introduced until version 1.9.20:

That is a very good find. The call to checkDecompiledText is not made directly by KtlintRuleEngine. I would need the full stack trace to find the root cause of it.

I can do one better. I've created a small demo project along with some usage instructions at the following location:
