## Getting Binaries
You can find binaries and dependency information for Maven, Ivy, Gradle, SBT, and others at [http://search.maven.org](https://search.maven.org/search?q=g:io.reactivex.rxjava3%20AND%20rxjava).
Example for Maven:
```xml
<dependency>
<groupId>io.reactivex.rxjava3</groupId>
<artifactId>rxjava</artifactId>
<version>3.0.4</version>
</dependency>
```
and for Ivy:
```xml
<dependency org="io.reactivex.rxjava3" name="rxjava" rev="3.0.4" />
```
and for SBT:
```scala
libraryDependencies += "io.reactivex" %% "rxscala" % "0.26.5"
libraryDependencies += "io.reactivex.rxjava3" % "rxjava" % "3.0.4"
```
and for Gradle:
```groovy
implementation 'io.reactivex.rxjava3:rxjava:3.0.4'
```
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
<?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>io.reactivex.rxjava3</groupId>
<artifactId>rxjava</artifactId>
<version>3.0.4</version>
<name>RxJava</name>
<description>Reactive Extensions for Java</description>
<url>https://github.com/ReactiveX/RxJava</url>
<dependencies>
<dependency>
<groupId>io.reactivex.rxjava3</groupId>
<artifactId>rxjava</artifactId>
<version>3.0.4</version>
</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.
### Snapshots
Snapshots are available via [JFrog](https://oss.jfrog.org/libs-snapshot/io/reactivex/rxjava3/rxjava/):
```groovy
repositories {
maven { url 'https://oss.jfrog.org/libs-snapshot' }
}
dependencies {
compile 'io.reactivex.rxjava3:rxjava:3.0.4'
}
```
## 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
```
