Error trying to run: 'Error: Could not find or load main class fr.jbrunet.home.admin.backend.HABApplication'

[faridg18]

Tried running the example and ran into a problem: 'Error: Could not find or load main class fr.jbrunet.home.admin.backend.HABApplication' when running java -jar target/dw-websocket-example.jar

Any ideas on what's wrong?
