Compilation error when using AsciidoctorTask with @CompileStatic in Groovy project

[artemy-osipov]

When writing a Gradle plugin in Groovy with @CompileStatic, referencing AsciidoctorTask causes a compilation error.
The same code in Kotlin only produces a warning.

Steps to Reproduce

Use a classic variant of plugin

dependencies {
    implementation("org.asciidoctor.jvm.convert.classic:org.asciidoctor.jvm.convert.classic.gradle.plugin:5.0.0-alpha.1")
    ...
}

Use @CompileStatic and reference AsciidoctorTask class

package example

import groovy.transform.CompileStatic
import org.asciidoctor.gradle.jvm.AsciidoctorJPlugin
import org.asciidoctor.gradle.jvm.AsciidoctorTask
import org.gradle.api.Plugin
import org.gradle.api.Project

@CompileStatic
class DocumentationPlugin implements Plugin<Project> {

    @Override
    void apply(Project project) {
        project.plugins.apply(AsciidoctorJPlugin)

        project.tasks.withType(AsciidoctorTask).configureEach {
            it.baseDirFollowsSourceFile()
        }
    }
}

Run ./gradlew clean check

➜  asc-example ./gradlew clean check

A result for a kotlin project

> Task :compileKotlin
DocumentationPlugin.kt:14:16 Cannot access 'SerializableWorkerAppParameters' which is a supertype of 'AbstractAsciidoctorTask' or one of its arguments. This may be forbidden soon. Check the module classpath for missing or conflicting dependencies.

Adding grolifant5-rawhide to your runtime classpath should solve the problem.

Also, if you can, try to migrate to the new model, as the classic plugins will be dropped in 6.0.

Thank you, adding grolifant5-rawhide solves the issue. As a workaround, removing the @CompileStatic annotation also avoids the error.

I’ve tried migrating to the new model, but I ran into a groovy-nio incompatibility error. Still digging into that.

Feel free to post that error message. It could also be an upstream error.
