IBM Cloud foundry java services app: Class Not found exception

Question

I'm trying to run my java app on ibm bluemix. The app is deployed succesfully but it's unable to start. The logs contain an error message:

Error: 2018-10-26T11:25:08.85+0530 [APP/PROC/WEB/0] ERR Error: Could not find or load main class com.afpva.retrain.identify.RPConfigApplication

It's working as expected in the local environment. My manifest file is as follows:

applications:
- path: target/afpva-retraining-identify-service-0.0.1-SNAPSHOT.war
  memory: 128M
  instances: 1
  name: afpva-retraining-identify-service
  host: afpva-retraining-identify-service
