Error on `forkedSpringBootRun` task: BootRun_Decorated cannot be cast to BootRun

[juanituxx]

Hello there,

First of all, thanks for the plugin and for reading my problem/issue.

I have done everything to try to mnake the plugin run with my actual SpringBoot App, but I don't manage to make it work.

Spring Boot Version: 2.7.12

I do have my openapi.gradle and common.gradle (which is loaded after on the build.gradle)

common.gradle:

buildscript {
    repositories {
        gradlePluginPortal()
        mavenCentral()
    }
    dependencies {
        classpath 'org.sonarsource.scanner.gradle:sonarqube-gradle-plugin:2.7.1'
        classpath 'gradle.plugin.com.palantir.gradle.docker:gradle-docker:0.22.1'
        classpath 'io.spring.gradle:dependency-management-plugin:1.0.2.RELEASE'
        classpath 'net.saliman:gradle-properties-plugin:1.4.6'
    }
}

apply plugin: org.gradle.api.plugins.JavaPlugin
apply plugin: io.spring.gradle.dependencymanagement.DependencyManagementPlugin
apply plugin: org.gradle.testing.jacoco.plugins.JacocoPlugin
apply plugin: org.gradle.api.plugins.quality.CheckstylePlugin
apply plugin: org.sonarqube.gradle.SonarQubePlugin
apply plugin: com.palantir.gradle.docker.PalantirDockerPlugin
apply plugin: net.saliman.gradle.plugin.properties.PropertiesPlugin

openapi.gradle:

buildscript {
    repositories {
        gradlePluginPortal()
        mavenCentral()
    }
    dependencies {
        classpath "org.springdoc.openapi-gradle-plugin:org.springdoc.openapi-gradle-plugin.gradle.plugin:1.9.0"
    }
}

apply plugin: org.springdoc.openapi.gradle.plugin.OpenApiGradlePlugin

openApi {
	apiDocsUrl.set("https://localhost:9000/api/docs")
	outputDir.set(file("docs/swagger"))
	outputFileName.set("swagger.json")
	waitTimeInSeconds.set(10)
}

build.gradle:

plugins {
    id "com.github.psxpaul.execfork" version "0.2.0"
    id "org.springframework.boot" version "${sprinbootVersion}"
}

apply from: "$rootDir/scommon/config/gradle/common.gradle"`
apply from: "$rootDir/common/config/gradle/openapi.gradle"

Project compiles perfectly, all task work, SpringBoot is able to boot application with bootRun.
BUT when I run the generateOpenApiDocs task as: gradle generateOpenApiDocs I get an error and I don't know if I'm having problems with the versions I am using or what icompatibility is going on:

Exception is:

I am not super keen in Gradle, but it seems that there might be a problem not on my side? Or what's going on any clue?

Thanks in advance for your help.
