SourceSet with name 'jvmMain' not found

Question

I'm trying to run kotlin multiplatform project with jvm and js source sets but am getting the following error:

FAILURE: Build failed with an exception.

* Where:
Initialization script '/private/var/folders/yc/sdfads/T/Home_main__.gradle' line: 20

* What went wrong:
A problem occurred configuring root project 'kotlin-multiplatform'.
> Could not create task ':Home.main()'.
   > SourceSet with name 'jvmMain' not found.

Home is the a class in src/jvmMain/kotlin/Home.kt and only has a main() function.

I tried to follow the docs as close as possible, there is not much of my own code. I just set the jvmMain source set to depend on commonMain and add a couple more libraries. My build.gradle:

plugins {
    kotlin("multiplatform") version "1.3.72"
}

kotlin {
    jvm()
    js().browser()
//    android()

    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation(kotlin("stdlib-common"))
            }
        }
        val commonTest by getting {
            dependencies {
                implementation(kotlin("test-common"))
                implementation(kotlin("test-annotations-common"))
            }
        }
        jvm().compilations["main"].defaultSourceSet {
            dependsOn(commonMain)
            dependencies {
                implementation(kotlin("stdlib"))
                ...
            }
        }
    }
}

The project builds fine but when I run it, I get

SourceSet with name 'jvmMain' not found.

Can anybody see what I'm missing, or is anyone hitting the same issue?
