Vavr is an **object-functional extension for Java that makes defensive programming easy by leveraging immutability and functional control structures**

Vavr seamlessly combines object-oriented programming with the elegance and robustness of functional programming. 

It provides:
* persistent collections
* functional abstractions for error handling, concurrent programming
* pattern matching
* ...and more

Since **Vavr has no dependencies** beyond the JVM, you can easily add it as a standalone .jar to your classpath.

## Using Vavr

See [User Guide](http://docs.vavr.io) and/or [Javadoc](http://www.javadoc.io/doc/io.vavr/vavr).

### Useful Maven Goals

* Executing tests: `mvn clean test`
* Executing doclint: `mvn javadoc:javadoc`
* Executing code coverage report: `mvn -P ci clean test jacoco:report`
* Create -javadoc.jar: `mvn javadoc:jar`
* Create -source.jar: `mvn source:jar`

### Contributing

Currently, there are two significant branches:
- `main` (represents a stream of work leading to the release of a new ma version)
- `version/1.x` (historical work that went into `1.0.0-alpha-3`, treat is as read-only - will be kept around for cherry-picking)

A small number of users have reported problems building Vavr. Read our [contribution guide](./CONTRIBUTING.md) for details.
