NoClassDefFoundError when running jar file

Question

I am trying to run a jar file using the command java -jar Parser/build/libs/CSVParser-1.0-SNAPSHOT.jar but it is showing me an exception

Exception in thread "main" java.lang.NoClassDefFoundError: kotlin/Pair
   at server.MainKt.main(Main.kt:16)
   at server.MainKt.main(Main.kt)
Caused by: java.lang.ClassNotFoundException: kotlin.Pair
   at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:581)
   at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:178)
   at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521)
   ... 2 more

This is what the MANIFEST.MF looks like

Manifest-Version: 1.0
Main-Class: server.MainKt

I think it's not able to find the class defined at line number 16 of the file.

        )

    val getMethod = GetMethod(mapOfGetPaths)
    val postMethod = PostMethod(mapOfPostPaths)

    Server(3000, getMethod, postMethod).listenForRequests()
}

BadRequest, HomePath, FileContent, GenrateErrors, GetMethod, PostMethod, are classes from different Packages
