Prevent imported types containing generic types

[dimber-cais]

If a class mapping is performed with generics, for example

configure<JSONSchemaCodegen> {
    packageName.set("com.example")
    classMappings {
        byExtension("kotlin.collections.Map<String, Any?>", "x-polymorphic", "true")
    }
}

Then the resulting import in the generated code looks like:

package com.example

import kotlin.collections.Map<String, Any?>

data class Example(
   ...
)

I think it might be an easy fix to change the following function in Target from:

    fun addImport(classId: ClassId) {
        if (!samePackage(classId))
            imports.addOnce(classId.qualifiedClassName)
        localImports.addOnce(classId)
    }

to:

    fun addImport(classId: ClassId) {
        if (!samePackage(classId))
            imports.addOnce(classId.qualifiedClassName.substringBefore('<'))
        localImports.addOnce(classId)
    }

Alternatively, this could be changed to be stripped off when processing the className within the various CustomClass sublcass constructors.

I think allowing generics would be more difficult than you suggest, but the main reason I haven't put any effort into it is that there is a simple workaround.

If you create a typealias as follows:

typealias MapStringAny = Map<String, Any>

then you can use MapStringAny in your classMappings setting. It may not be ideal, but it gets around the problem with relatively little effort.
