Getting Binaries

You can find binaries and dependency information for Maven, Ivy, Gradle, SBT, and others at http://search.maven.org.

Example for Maven:

<dependency>
    <groupId>io.reactivex</groupId>
    <artifactId>rxjava</artifactId>
    <version>1.0.0</version>
</dependency>

and for Ivy:

<dependency org="io.reactivex" name="rxjava" rev="1.0.0" />

and for SBT:

libraryDependencies += "com.netflix.rxjava" % "rxjava-scala" % "1.0.0"

and for Gradle:

compile 'io.reactivex:rxjava:1.0.0'

If you need to download the jars instead of using a build system, create a Maven pom file like this with the desired version:

<?xml version="1.0"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.netflix.rxjava.download</groupId>
    <artifactId>rxjava-download</artifactId>
    <version>1.0-SNAPSHOT</version>
    <name>Simple POM to download rxjava and dependencies</name>
    <url>http://github.com/ReactiveX/RxJava</url>
    <dependencies>
        <dependency>
            <groupId>io.reactivex</groupId>
            <artifactId>rxjava</artifactId>
            <version>1.0.0</version>
            <scope/>
        </dependency>
    </dependencies>
</project>

Then execute:

$ mvn -f download-rxjava-pom.xml dependency:copy-dependencies

That command downloads rxjava-*.jar and its dependencies into ./target/dependency/.

You need Java 6 or later.

Building

To check out and build the RxJava source, issue the following commands:

$ git clone git@github.com:ReactiveX/RxJava.git
$ cd RxJava/
$ ./gradlew build

To do a clean build, issue the following command:

$ ./gradlew clean build

A build should look similar to this:

$ ./gradlew build
:rxjava:compileJava
:rxjava:processResources UP-TO-DATE
:rxjava:classes
:rxjava:jar
:rxjava:sourcesJar
:rxjava:signArchives SKIPPED
:rxjava:assemble
:rxjava:licenseMain UP-TO-DATE
:rxjava:licenseTest UP-TO-DATE
:rxjava:compileTestJava
:rxjava:processTestResources UP-TO-DATE
:rxjava:testClasses
:rxjava:test
:rxjava:check
:rxjava:build

BUILD SUCCESSFUL

Total time: 30.758 secs

On a clean build you will see the unit tests run. They will look something like this:

> Building > :rxjava:test > 91 tests completed

Troubleshooting

One developer reported getting the following error:

Could not resolve all dependencies for configuration ':language-adaptors:rxjava-scala:provided'

He was able to resolve the problem by removing old versions of scala-library from .gradle/caches and .m2/repository/org/scala-lang/ and then doing a clean build. (See this page for details.)

You may get the following error during building RxJava:

Failed to apply plugin [id 'java'] Could not generate a proxy class for class nebula.core.NamedContainerProperOrder.

It's a JVM issue, see GROOVY-6951 for details. If so, you can run export GRADLE_OPTS=-noverify before building RxJava, or update your JDK.

Something went wrong with that request. Please try again.
