Devpod watch.sh location?

[sdoxsee]

I used 'jx create spring' and have a git repository and everything else. However, when i do 'jx create devpod --sync --reuse' I get into the pod but there is no watch.sh script that builds my image to test (as per https://jenkins-x.io/developing/devpods/#example-workflow-with-an-existing-project). At what point does the watch.sh appear or is that not part of the spring project and only quickstart? Thanks!

Update: Just found more documentation

So once the skaffold dev -p dev (what watch.sh does)

Now I can see it built and I can go to the url. (NOTE: still not sure why there was no watch.sh...perhaps this was removed and the documentation needs updating)

However, it still doesn't seem to be watching my changes. Maybe the error below is why

skaffold dev -p dev

must be my DOCKER_REGISTRY is undefined....tracking that down

BTW I fixed the DOCKER_REGISTRY issue yesterday. If you do jx upgrade platform and delete and recreate your devpod jx delete devpod && jx create devpod it should be fine again.

On the watch.sh really those scripts were temporary hacks until skaffold did all the awesome via skaffold dev; though we've only watch.sh scripts in the quickstarts for node + go right now:

• https://github.com/jenkins-x-quickstarts/node-http/blob/master/watch.sh
• https://github.com/jenkins-x-quickstarts/golang-http/blob/master/watch.sh

the aim is to move towards just using vanilla skaffold really. We're super close to moving back to the upstream skaffold now. Now the remaining known regression was fixed: GoogleContainerTools/skaffold#741

we just need the next release and we're good to go.

BTW we're hoping to use a slightly different approach to give a nice developer feedback for working with Java/Spring: #833

Thanks @jstrachan. Very helpful comment and super cool project. I'm enjoying the experience! I'll close this and look forward to the coming improvements. Cheers.
