Trying to use Kotlin-gradle plugin from local url

I'm trying to setup the gradle-kotlin-plugin locally, but it doesnt work at all. Im using Gradle 4.9 and Kotlin version 1.2.71. The Gradle sync fails and this exceptions is thrown:

org/jetbrains/kotlin/cli/common/PropertiesKt

NoClassDefFoundError: org/jetbrains/kotlin/cli/common/PropertiesKt

Im put all needed resources into the directory /lib/kotlin, meaning kotlin-gradle-plugin-1.2.71.jar, kotlin-stdlib-1.2.70.jar,kotlin-stdlib-1.2.70.pom,kotlin-stdlib-common-1.2.70.jar,kotlin-stdlib-common-1.2.70.pom. If i set the repo to url "https://plugins.gradle.org/m2/" everything is working fine(i always want to load the plugin from the local file and NOT from the online repo). The other kotlin dependencies are also included.

build.gradle

 buildscript {
        ext.kotlin_version = '1.2.71'
        repositories {
        flatDir dirs: '/lib/kotlin'
        mavenLocal()
        maven{
            url uri('lib/kotlin')
        }
 dependencies {

        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"


    }
    ...
    allprojects {
    apply plugin: 'java'
    apply plugin: 'application'
    apply plugin: "kotlin"
    ..
    dependencies {
        compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

Edit: Now the plugin is working but Kotlin is not compiling and is telling me:

  Could not perform incremental compilation: Could not connect to Kotlin compile daemon
Could not connect to kotlin daemon. Using fallback strategy.
