You should consider a root Build.kt that loads other Build.kt from its modules. For example, say you have the following project structure:

project_root/kobalt/src/Build.kt
project_root/moduleA/kobalt/src/Build.kt
project_root/moduleB/kobalt/src/Build.kt

then Root project should have a descriptor similar to:

val project = modularProject {
    modules(“moduleA”, “moduleB”)
}

When building we should have the option to say:

./kotlinw assemble —module moduleA

This is because of module dependencies.
