Try two things: 1. Use the -p command to target your deployable artifact. This would look something like cf p APP_NAME -p PATH_TO_YOUR_WAR. I usually chain my build and deploy commands so: mvn clean package && cf p APP_NAME -p PATH_TO_YOUR_WAR.

2. If this doesn't work then you can specify a build pack. So cf p APP_NAME -p PATH_TO_YOUR_WAR -b SOME_BUILDPACK. You can see the available build packs by calling cf buildpacks.

Hope this helps.

When deploying first time your app on cloud foundry then following command will not work

cf push TestService

you need to use following command

cf push -p  TestService-0.0.1-SNAPSHOT.jar testService

Else add manifest.yml on root

applications:
- name: Demo
  memory: 2G
  disk_quota: 2G
  instances: 1
  path: target/demo-local-0.0.1-SNAPSHOT.jar
  env: 
    SPRING_PROFILES_ACTIVE : "dev"

routes:
- route: demo.app.dev.vk.vaquar.khan.com

after that go to path and run cf push < JAR_NAME>
