Spring Statemachine 1.2.2.RELEASE is built and tested with JDK 8(all artifacts have JDK 7 compatibility) and Spring Framework 4.3.3.RELEASE and doesn’t require any other dependencies outside of Spring Framework within its core system.

Other optional parts like Chapter 29, Using Distributed States has dependencies to a Zookeeper, while Part VI, “State Machine Examples” has dependencies to spring-shell and spring-boot which pulls other dependencies beyond framework itself. Also optional security and data access has dependencies to Spring Security and Spring Data Modules.
