./gradlew run###Tip: if you're creating a new project and you're faced with the problem with jcenter being discontinued, do this:
change the code in the build.gradle.kt file from:
repositories {
   jcenter()
   mavenCentral()
}
dependencies {
   testImplementation(kotlin("test"))
   implementation("org.jetbrains.kotlinx:kotlinx-html:0.7.2")
}to:
repositories {
   maven(url = "https://maven.pkg.jetbrains.space/public/p/kotlinx-html/maven")
   mavenCentral()
}
dependencies {
   testImplementation(kotlin("test"))
   implementation("org.jetbrains.kotlinx:kotlinx-html-js:0.7.3")
