k8s:watch with jkube.watch.mode=copy doesn't work

[rohanKanojia]

Describe the bug

k8s:watch goal when run in Docker mode has various modes, see Watcher Docker Image documentation.

One of them is copy mode where changed files are directly copied to the root directory of the running container. It's pretty handy with web applications where applications could be redeployed by just copying updated war files.

This doesn't seem to be working at the moment.

Steps to reproduce

1. In a tomcat/jetty based project, run mvn k8s:build k8s:resource k8s:apply k8s:watch -Djkube.watch.mode=copy
2. In another terminal make some changes to project and run mvn package
3. Instead of files getting copied into container, you'd see error message in k8s:watch logs. Application changes are also not reflected in deployed pod.

Expected behavior

mvn k8s:watch -Djkube.watch.mode=copy should copy changed files into container when mvn package is run
