Debugging custom OR with IntelliJ

Custom Deployment
1

Hi,
I have a lot of java code not working since OR stopped working with sub-modules. I already found the reason for some errors but I would need to know if it has more implications in the code by debugging the code. For this reason I want to run OR from IntelliJ, I used to be able to do it without any problem, but now I can’t do it.

The documentation still references using the ‘openremote’ folder which now doesn’t exist using artifacts (i.e. To run the manager app run npm run serve from the /openremote/ui/app/manager directory, or references to this folder inside dev-testing.yml).

If I run the ‘Custom deployment’ configuration from IntelliJ the error is:

INFO [main ] remote.manager.setup.KeycloakInitService : Connecting to Keycloak server: http://127.0.0.1:8081/auth
INFO [main ] remote.manager.setup.KeycloakInitService : Keycloak server not available, waiting...

I’m probably failing in some configuration issue, any hints?

Well, I fixed the keycloak problem by cloning the openremote repository to another location and running dev-testing.yml (changing the path), although I’m not sure if this is the right way to do it. Now I need to see the interface in the web browser, I didn’t manage to run the manager, npm doesn’t work in this case… any ideas please?

It’s probably this known issue:

If you have a project based on our custom-project template you can run the “Custom Deployment” configuration in IntelliJ IDEA. When it has finished starting you can login to the Manager UI locally via using http://localhost:8080/manager in your browser.

When doing Manager UI development also run npm run serve in the /ui/app/manager directory of your openremote/openremote repository clone. Then you can use http://localhost:9000/manager/ and the browser will automatically reload after making Manager UI changes.

Hi, it almost works, but it doesn’t

I can see the manager UI in the browser, happy with this, but every 30s the page refreshes and if I’m viewing the graph of some attribute it closes and I have to start again, it’s very annoying. Without any agent/asset I can see the following on the console, just every 30s. Finally I’m using OR 1.2.1 (my java code does not work with newer versions)

It doesn’t work either, although I think this is not necessary for what I want to do, just debug java code, which is the case above and it works except for those “reboots” every 30s.
With npm the error is:

> @openremote/manager@1.3.3 serve
> npx tsc -b --clean && npx shx rm -rf dist lib && npx orutil build && npx cross-env NODE_OPTIONS=--max_old_space_size=4096 webpack serve --mode development
                                                       
                This is not the tsc command you are looking for                                                                 

To get access to the TypeScript compiler, tsc, from the command line either:

- Use npm install typescript to first add TypeScript to your project before using npx
- Use yarn to avoid accidentally running code from un-installed packages
