一、编译配置

1、Android中的配置

使用如下方式开启在Android中的gradle的kotlin编译配置：
该配置在其余平台不可用

android {...compileOptions {sourceCompatibility JavaVersion.VERSION_17targetCompatibility JavaVersion.VERSION_17}kotlinOptions {jvmTarget = '1.8'
//        freeCompilerArgs.add("-Xexport-kdoc")setFreeCompilerArgs(["-Xcontext-receivers"])
//setFreeCompilerArgs(["-Xexport-kdoc","-Xcontext-receivers","-opt-in=org.mylibrary.OptInAnnotation"])}//如下方式会报错//tasks.withType(KotlinCompile::class).all {
//    kotlinOptions.freeCompilerArgs = listOf("-Xcontext-receivers")
//}...}

以上配置会开启Kotlin/JVM 的上下文接收者原型功能，否则该功能不可用，开启后编码可以使用以下代码：

interface LoggingContext {val log: Logger // This context provides a reference to a logger 
}context(LoggingContext)
fun startBusinessOperation() {// You can access the log property since LoggingContext is an implicit receiverlog.info("Operation has started")
}fun test(loggingContext: LoggingContext) {with(loggingContext) {// You need to have LoggingContext in a scope as an implicit receiver// to call startBusinessOperation()startBusinessOperation()}
}

传递参数的发过誓可以直接在里面写setFreeCompilerArgs(["-opt-in=org.mylibrary.OptInAnnotation"])

2、其余平台的配置

除了上述配置还可以使用以下配置，该配置可以在其余平台使用:

android {
}
tasks.withType(org.jetbrains.kotlin.gradle.tasks.KotlinCompile).all {sourceCompatibility = JavaVersion.VERSION_1_8targetCompatibility = JavaVersion.VERSION_1_8kotlinOptions {jvmTarget = '1.8'apiVersion = '1.1'languageVersion = '1.1'}
}
