Building from Source

Spring Statemachine uses a Gradle-based build system. In the instructions below, ./gradlew is invoked from the root of the source tree and serves as a cross-platform, self-contained bootstrap mechanism for the build.

Prerequisites

Git and the JDK8 build.

Be sure that your JAVA_HOME environment variable points to the jdk folder extracted from the JDK download. While build requires JDK8, created artifacts are JDK7 compatible.
