# Repro project for Kotlin compiler bug [KT-36297](https://youtrack.jetbrains.com/issue/KT-36297)
When `-XXLanguage:+NewInference` is set, the Kotlin compiler emits a reference to a
nonexisting class for code with nested inline lambdas.
This prevents the type of the generated `Callable` to be inspected via reflection at runtime.
To reproduce the bug simply run the provided app (or the tests):
```
$ ./kotlin-dsl-inline-repro » ./gradlew :app:run -q 1 ↵

```
Or run the tests:
```
$ ./kotlin-dsl-inline-repro » ./gradlew check
> Task :app:test FAILED
repro.ReproTest > provider type is inferred from Callable generic interface argument FAILED
java.lang.NoClassDefFoundError at ReproTest.kt:28

The failure stacktrace should be basically the same as before:

## Structure
To better match the issue affecting Gradle users, this project replicates the involved Gradle types and DSL structure.
* `api` contains a simplified version of the Java Gradle API required to reproduce the bug
* `dsl` contains the two inline Kotlin extensions required to reproduce the bug
* `app` puts together the dsl and api to reproduce the bug
