How to create a new Intellij plugin LanguageFileType based on Kotlin?

c

I want to create a new LanguageFileType to support Kotlin inspection on my script language file with an extension "engine.kts". but there is an issue with getting the KotlinLanguage instance.

I already tried this way but it throws NullPointerException.

        Language.findLanguageByID("kotlin")
Solution
    1. Add Kotlin Dependency to your plugin.xml file.

    1. Add compileOnly configuration to Gradle project dependency.
    compileOnly("org.jetbrains.kotlin:kotlin-compiler")
