LanguageSettings 2.0.0-RC1 API

All Implemented Interfaces:
```
public interface LanguageSettings

                    
```
Represents most common Kotlin compilation settings for an entity.
Note: This interface is soft-deprecated. Instead, better to use existing compilerOptions DSL.
See also Compiler options DSL documentation.

  - getLanguageVersion
```
 abstract String getLanguageVersion()
```
    Provides source compatibility with the specified version of Kotlin.
    Possible values: "1.4 (deprecated)", "1.5 (deprecated)", "1.6", "1.7", "1.8", "1.9", "2.0 (experimental)", "2.1 (experimental)".
    Default value: null
  - getApiVersion
```
 abstract String getApiVersion()
```
    Allows using declarations only from the specified version of bundled libraries.
    Possible values: "1.4 (deprecated)", "1.5 (deprecated)", "1.6", "1.7", "1.8", "1.9", "2.0 (experimental)", "2.1 (experimental)".
    Default value: null
  - getProgressiveMode
```
 abstract Boolean getProgressiveMode()
```
    Enables progressive compiler mode.
    In this mode, deprecations and bug fixes for unstable code take effect immediately, instead of going through a graceful migration cycle. Code written in progressive mode is backward compatible. However, code written in non-progressive mode may cause compilation errors in progressive mode.
    Default value: false
  - getOptInAnnotationsInUse
```
 abstract Set<String> getOptInAnnotationsInUse()
```
    Enables use of any API that requires opt-in with an opt-in requirement marker containing its fully qualified name.
    Default value: emptyList<String>()
