I am unable to run the kotlin-server generated by Swagger editor. I am on Windows machine

I downloaded the kotlin-server-server-generated.zip, unzipped it at C:\Users\manu\Documents\manu\kotlin-server-server-generated, opened Readme.MD file and followed the instructions in it.

Using Windows cmd, In C:\Users\manu\Documents\manu\kotlin-server-server-generated, first I ran gradle wrapper

I got this output

Starting a Gradle Daemon, 1 incompatible and 2 stopped Daemons could not be reused, use --status for details
Build cache is an incubating feature.

BUILD SUCCESSFUL in 17s
1 actionable task: 1 executed

Then I ran gradlew check assemble

Using TaskInputs.file() with something that doesn't resolve to a File object has been deprecated and is scheduled to be removed in Gradle 5.0. Use TaskInputs.files() instead.

Then I ran java -jar ./build/libs/kotlin-server.jar

But when I pointed the browser to localhost:8080, I see Page Not Found.

I even tried running kotlin-server.bat directly in CMD but got error Error: Could not find or load main class io.ktor.server.netty.DevelopmentEngine

What am I doing wrong?
