./gradlew test - ArrayIndexOutOfBoundsException: 450

After cloning the project I tried to run the tests with ./gradlew test but it continues to throw a 'ArrayIndexOutOfBoundsException`

Davids-MBP-2:kotlin-koans david$ ./gradlew test
e: java.lang.ArrayIndexOutOfBoundsException: 450

In my case, the IDE notified me of the issue. The gradle file shows this warning

After setting the version to 1.2.50 compilation succeeds!

buildscript {
    ext.kotlin_version = '1.2.0'

    repositories {
        mavenCentral()
    }

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