Hey guys when i’m trying to build my project with gradle, kotlin compile crashed with unresolved reference error for every com.sun - Package. If i run the project it works very well

Envirnonment:

OS:           Mac OS X 10.14.1 x86_64

Background:
My goal is to write a debugger. So i need some classes from the jdi

build.gradle

plugins {
    id 'org.jetbrains.kotlin.jvm' version '1.3.0'
}

group 'de.test.rev'
version '1.0-SNAPSHOT'

repositories {
    mavenCentral()
}

jar {
    manifest {
        attributes 'Main-Class': 'de.test.rev.MainKt'
    }

    from {
        configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
    }
}

dependencies {
    compile "org.jetbrains.kotlin:kotlin-stdlib-jdk8"
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testImplementation(
            'org.junit.jupiter:junit-jupiter-api:5.3.0'
    )
    testRuntimeOnly(
            'org.junit.jupiter:junit-jupiter-engine:5.3.0'
    )
    compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.0.0'


}

compileKotlin {
    kotlinOptions.jvmTarget = "1.8"
}
compileTestKotlin {
    kotlinOptions.jvmTarget = "1.8"
}

Error-Message
e: /pathToProject/src/main/kotlin/de/test/rev/debug/facade/DebugFacade.kt: (3, 16): Unresolved reference: jdi

followed by a ton of errors for other com.sun. packages.

What I have tried so far

  • removed ./idea, .gradle and build Folder
  • create a new project

It is possible that for some reason, the build process does use the openjdk? If I rembered correct, sun packages are not be in that package

I solved it by myself by adding the sun librariers to the jar.

Adding the following to the dependencies block:

compile files("${System.getProperty('java.home')}/../lib/tools.jar")
