Jar file not in target folder after building with maven - KOTLIN

Question

I am a JAVA developer but am trying to move to Kotlin, which tells that am new to Kotlin. I have a kotlin maven project where I implement vertx using intellij IDEA. Below is the build part of the pom file.

My concern is that when I build the project using the IDEA, the jar file is not generated into the target folder. I did follow the instructions from kotlinlang page to setup the POM file but the issue still persist.

<build>
        <plugins>
            <plugin>

This question would have been a duplicate if it was easily detected. I kept on googling and searching with different search queries until I got to @arghtype's answer on this SO page.

The answer suggested you specifically build the project with maven goal. Intellij has a maven projects window on the left side of the main window which is usually minimized.

When you click and the maven project window opens

drop down the lifecycle and double click clean.
when cleaning is done double click again on the package.
That's all...check the target folder, you will see the jar file(s).
