# Decisioning Logic
## Positive Signals ✅
### Only Kotlin `.kt` Source Files
### Using Kotlin JVM Plugin
### Uses the Kotlin Multiplatform Plugin
* NOTE: We could check the configuration in the future to see if it has multiple targets if deemed important.

## Negative Signals ❌
### Are there any java imports in the source files?
Imports starting with `java.`, etc.
* Iterate through all `main` sourcesets for a simple `.contains("import java.")` List of all java stdlib packages: https://docs.oracle.com/en/java/javase/11/docs/api/java.base/module-summary.html
* NOTE: This wouldn't find fully qualified references, but that could be added later if deemed important.
### Any non-multiplatform dependencies?
Search for transitive artifacts that are not multiplatform compatible
* Use a list of well known libraries that are known to be multiplatform compatible, but then using the Maven Search API to look for the presence of the `kotlin-tooling-metadata.json` object via their JSON API at https://search.maven.org/.
  * Example request for `ktor-client-core`: https://search.maven.org/solrsearch/select?q=g%3Aio.ktor+AND+a%3Aktor-client-core+AND+v%3A2.1.0+AND+p%3Ajar+AND+l%3Akotlin-tooling-metadata&rows=1&wt=json
* NOTE: These results would be cached, the same way dependencies are today.
* NOTE: We could traverse local module dependencies, and check theirs as well if deemed important.  
### Is this an Android Library Module?
This tool works on `kotlin("jvm")` modules.  If you are looking to move Android Libraries to Kotlin Multiplatform, the [dependency-analysis-android-gradle-plugin](https://github.com/autonomousapps/dependency-analysis-android-gradle-plugin) will help give you advice on which modules can become `kotlin("jvm")` modules.  After that, come back and use `kmp-ready`.

# `kmpReady` Gradle Task
Could be applied to a specific module or the root so that all modules are scanned.

Run the `kmpReady` task and get a result like this:
