spring statemachine - problems running state machine examples -

congratulations on spring state machine, found yesterday , have been trying out, turnstile example running in sts. found easy , intuitive build fsm.

because spring shell doesn't work in sts tracked down instructions run examples command line in reference doc,

"java -jar spring-statemachine-samples-turnstile-1.0.0.build-snapshot.jar"

, running got error

"no main manifest attribute, in spring-statemachine-samples-turnstile-1.0.0.build-snapshot.jar".

although not novice in using gradle, tried fixing adding line build.gradle in jar section

"manifest.attributes['main-class'] = 'demo.turnstile.application'" (which doesn't handle various sub-projects know) got error "noclassdeffounderror: org/springframework/shell/bootstrap".

if possible run samples gradle, include them in reference document? tried running samples using

gradle run there no interaction shell scripts.

samples designed run executable jar , shell can interact without need recompile every change. error indicates didn't build sample jar mentioned in docs.

./gradlew clean build -x test 

this automatically use spring boot plugin add necessary jar manifest headers jar meta info make true executable jar. every every sample spring boot app.
