spring-cloud-dataflow-server-yarn is no longer actively maintained by VMware, Inc.

== Spring Cloud Data Flow Server for Apache Yarn

The Spring Cloud Data Flow team have been happy stewards of this project, but we are focusing our efforts towards Local, Kubernetes and Cloud Foundry implementations going forward, so the Spring Cloud Data Flow team will no longer maintain it.

However, we are looking to donate the project to the community. If you are interested in forking the project to continue to develop and maintaining it, we would be happy to cross-link and promote your forked project. Please ping us at https://gitter.im/spring-cloud/spring-cloud-dataflow[Gitter] to discuss it.

=== Building

Build and skip all tests:

./mvnw clean package -DskipTests

Or build project and run tests(tests take long time to run):

./mvnw clean package
