Gradle: Migrate from Groovy to Kotlin

What feature(s) would you like to see in RepoSense

Our current build.gradle script uses the Groovy syntax (example below):

plugins {
    id 'application'
    id 'checkstyle'
    id 'idea'
    id 'jacoco'
    id 'java'
    id 'com.github.johnrengelman.shadow' version '7.1.2'
    id 'com.liferay.node' version '7.2.18'
    id 'com.github.psxpaul.execfork' version '0.2.0'
    id 'com.palantir.git-version' version '0.13.0'
}

Is the feature request related to a problem?

Kotlin has been recommended due to cleaner syntax and enhanced editing experience in IDEs, particularly IntelliJ. Below shows the equivalent block in Kotlin syntax:

plugins {
    application
    checkstyle
    idea
    jacoco
    java
    id("com.github.johnrengelman.shadow") version "7.1.2"
    id("com.liferay.node") version "7.2.18"
    id("com.github.psxpaul.execfork") version "0.2.0"
    id("com.palantir.git-version") version "0.13.0"
}

One key advantage of Kotlin, imo, is that the syntax is much closer to that of Java, which we use for the backend, compared to Groovy. As an example, Groovy allows single and double quotes for strings whereas Kotlin requires strings to be in double-quotes, just like in Java.

Having a more standardised syntax means that someone who starts work on build.gradle.kts will find it easier to transition to the Java code.
