In a multi module Gradle project, ignore root project by default

Observed Behavior

In a multi-module Gradle project, after running apiDump, the file api/<projectName>.api will appear with a blank line.

Current workaround

I need to specifically ignore the root projects to avoid the creation of this file. This looks quite unnecessary:

For example,

apiValidation {
    ignoredProjects.addAll(subprojects.filter { it.name != "detekt-api"}.map { it.name } + rootProject.name)
}

Environment

The project uses a buildSrc and all scripts are in kts.

I did some further investigation and it is indeed that we have applied kotlin.jvm at the root project, but at the same time, I was wondering if there is no signature generated, should we even write the API file?

Good point.
