Línea de trabajo

Comienza con el repositorio de ejemplo enlazado y sus archivos build.gradle.kts y settings.gradle.kts, y luego ejecuta spotlessKotlinGradleApply en Spotless v8 para reproducir el fallo de inicialización del Parser. Compara la configuración de ktfmt con la configuración funcional de v7 e inspecciona cómo se inicializa ktfmt; se considera completado cuando ambos scripts de Kotlin Gradle se aplican correctamente sin NoClassDefFoundError.

Descripción

bug

Sample repo that reproduces the issue:
https://github.com/StefanLobbenmeierObjego/spotless-2646

This setup worked in spotless v7:

import com.diffplug.gradle.spotless.SpotlessExtension
configure<SpotlessExtension> {
    java {
        targetExclude(fileTree("${layout.buildDirectory}/generated") { include("**/*.java") })
        palantirJavaFormat("2.38.0")
    }

    kotlinGradle { ktfmt().kotlinlangStyle() }
}

After upgrading to v8 I get this error:

> Task :spotlessKotlinGradleApply FAILED
Caching disabled for task ':spotlessKotlinGradleApply' because:
  not worth caching
Task ':spotlessKotlinGradleApply' is not up-to-date because:
  Task has not declared any outputs despite executing actions.

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':spotlessKotlinGradleApply'.
> There were 2 lint error(s), they must be fixed or suppressed.
