kotlinx.coroutines

Library support for Kotlin coroutines. This is a companion version for Kotlin 1.1 release.

Modules

Basic modules:

• kotlinx-coroutines-core -- core primitives to work with coroutines.
• kotlinx-coroutines-jdk8 -- additional libraries for JDK8 (or Android API level 24).
• kotlinx-coroutines-nio -- extensions for asynchronous IO on JDK7+.

Modules that provide builders and iteration support for various reactive streams libraries:

• kotlinx-coroutines-reactive -- utilities for Reactive Streams
• kotlinx-coroutines-rx1 -- utilities for RxJava 1.x
• kotlinx-coroutines-rx2 -- utilities for RxJava 2.x

Modules that provide coroutine dispatchers for various single-threaded UI libraries:

• kotlinx-coroutines-android -- UI context for Android applications.
• kotlinx-coroutines-javafx -- JavaFx context for JavaFX UI applications.
• kotlinx-coroutines-swing -- Swing context for Swing UI applications.

Using in your projects

Note that these libraries are experimental and are subject to change.

The libraries are available via JCenter. These libraries require kotlin compiler version 1.1.x and require kotlin runtime of the same version as a dependency.

Maven

Add Bintray JCenter repository to <repositories> section:

<repository>
    <id>kotlinx</id>
    <url>https://kotlin.bintray.com/kotlinx/</url>
</repository>

Add dependencies (you can also add other modules that you need):

<dependency>
    <groupId>org.jetbrains.kotlinx</groupId>
    <artifactId>kotlinx-coroutines-core</artifactId>
    <version>0.14</version>
</dependency>

And make sure that you use the right Kotlin version:

<properties>
    <kotlin.version>1.1.1</kotlin.version>
</properties>

Gradle

Add Bintray JCenter repository:

repositories {
    `maven { url "https://kotlin.bintray.com/kotlinx/" }` 
}

Add dependencies (you can also add other modules that you need):

compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.14'

And make sure that you use the right Kotlin version:

buildscript {
    ext.kotlin_version = '1.1.1'
}
