I get this error when make two changes first, add the following dependency in my build.gradle file

dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$version_kotlin"
        classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:$navigationVersion"

Second add the line to my build.gradle(module) file 

apply plugin: 'androidx.navigation.safeargs'

You need to specify your navigationVresion like below

classpath "android.arch.navigation:navigation-safe-args-gradle-plugin:1.0.0-alpha01"

currently, you used a variable like navigationVersion but that variable is not defined in your Gradle file.
