How to --add-exports for kotlin project

[mgroth0]

I'd like to use some internal JavaFX code. I tried this:

allprojects {
    tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile::class.java).all {
        kotlinOptions {
            jvmTarget = "1.8"
//            freeCompilerArgs = listOf("--add-exports", "javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED")
        }
    }
    tasks.withType(JavaCompile::class.java).all {
        options.compilerArgs = listOf("--add-exports", "javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED")
        options.isFork = true // required for above?
        options.forkOptions.executable = "javac" // required for above?
    }
}

I tried using the --add-exports option in both the JavaCompile and KotlinCompile parts. For KotlinCompile I just get Invalid argument: --add-exports, and gradle doesn't even start the build. For JavaCompile the build runs fine but acts as if the option was not there and I get Symbol is declared in module 'javafx.graphics' which does not export package 'com.sun.javafx.tk'

A few things, your code could be simplified by doing the following:

allprojects {
    tasks.withType<org.jetbrains.kotlin.gradle.tasks.KotlinCompile> {
        kotlinOptions {
            jvmTarget = "1.8"
//            freeCompilerArgs = listOf("--add-exports", "javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED")
        }
    }
    tasks.withType<JavaCompile> {
        options.compilerArgs = listOf("--add-exports", "javafx.graphics/com.sun.javafx.tk=ALL-UNNAMED")
        options.isFork = true // required for above?
        options.forkOptions.executable = "javac" // required for above?
    }
}

Secondly, I don't think this is a Gradle Kotlin DSL issue, but instead seems like an issue/question about the Kotlin compiler. Perhaps you should try Stack Overflow or the Kotlin forums.

why options.isFork and options.forkOptions.executable is required for --add-epxorts?

@MERGHOOB apparently because of this
