Library support for Kotlin coroutines. This is a companion version for Kotlin 1.1.4 release (this is the minimal required Kotlin runtime version).

• kotlinx-coroutines-core -- core primitives to work with coroutines:
  • launch, async, produce, actor, etc coroutine builders;
  • Job and Deferred light-weight future with cancellation support;
  • CommonPool and other coroutine contexts;
  • Channel and Mutex communication and synchronization primitives;
  • delay, yield, etc top-level suspending functions;
  • select expression support and more.
• reactive -- modules that provide builders and iteration support for various reactive streams libraries:
  • Reactive Streams, RxJava 1.x and 2.x and Project Reactor.
• ui -- modules that provide coroutine dispatchers for various single-threaded UI libraries:
  • Android, JavaFx, and Swing.
• integration -- modules that provide integration with various asynchronous callback- and future-based libraries.
  • JDK8 CompletableFuture, Guava ListenableFuture, and synchronous networking/IO.

• Guide to kotlinx.coroutines by example (read it first)
• Guide to UI programming with coroutines
• Guide to reactive streams with coroutines
• Change log for kotlinx.coroutines
• Coroutines design document (KEEP)
• Full kotlinx.coroutines API reference

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

The libraries are published to kotlinx bintray repository and also linked to JCenter.

These libraries require kotlin compiler version 1.1.4 or later and require kotlin runtime of the same version as a dependency.

Add Bintray JCenter repository to <repositories> section:

<repository>
    <id>central</id>
    <url>https://jcenter.bintray.com</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>0.18</version>
</dependency>

And make sure that you use the right Kotlin version:

<properties>
    <kotlin.version>1.1.4</kotlin.version>
</properties>

Add Bintray JCenter repository:

repositories {
    jcenter()
}

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

compile 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.18'

And make sure that you use the right Kotlin version:

buildscript {
    ext.kotlin_version = '1.1.4'
}
