Getting started

In Maven:

<dependency>
    <groupId>co.paralleluniverse</groupId>
    <artifactId>quasar-core</artifactId>
    <version>0.6.2</version>
</dependency>

or, for JDK8:

<dependency>
    <groupId>co.paralleluniverse</groupId>
    <artifactId>quasar-core</artifactId>
    <version>0.6.2</version>
    <classifier>jdk8</classifier>
</dependency>

To use actors, add

<dependency>
    <groupId>co.paralleluniverse</groupId>
    <artifactId>quasar-actors</artifactId>
    <version>0.6.2</version>
</dependency>

For clustering support add:

<dependency>
    <groupId>co.paralleluniverse</groupId>
    <artifactId>quasar-galaxy</artifactId>

</dependency>

Or, build from sources by running:

./gradlew
