Component doesn`t reload in developer mode in Studio.

Hello everyone!

I developed component in IntelliJ + Talend Component Kit, and then run "deploy-in-studio", I recieved this message:

Installing development version of com.company:company-component:0.0.1-SNAPSHOT in C:\Talend\8.0.1\studio

[INFO] Studio C:\Talend\8.0.1\studio configured to use global maven repository, skipping artifact installation.

After this I need restart studio to refresh my component. I configure config.ini with some lines:

# use local .m2 instead of embedded studio one

maven.repository = global

# during development, see developer model part

component.environment = dev

# log into the console the component interactions - optional

component.server.jul.forceConsole = true

java.util.logging.SimpleFormatter.format = [%4$s] %5$s%6$s%n

But when I click on "Reload Component Kit Server" I recieve empty window and component doesn`t refresh:

Hi @Makar Pogorelov ,

a few questions...

As you've set the repository to global, do you redo a `mvn install` after each change to re-install modified artifact to global repo?

Please launch the studio from console as you've set force to console. Then when you click on refresh, catch the logs and send them in this topic...

How I can run studio from console?

I could start studio with console (-consoleLog param). When I click on "Reload component" console wrote:

[INFO] No TALEND-INF/plugins.properties found, will use file resolution

Hi,

From what I see above, no connectors are present! in ContainerManager (Components: [])

Could you send the whole log, your config.ini and components-registration.properties ?

hi,

Everything in logs seems fine., the connector is well loaded during startup.

Anyway, apparently we've a bug in connectors reloading as when you hit reload action the containers are empty. Will investigate as, from what I remember, we've an old opened issue on that.

Reloading component is mainly useful is you've made some changes in UI/Configuration. If it's runtime changes, just re running will update the connector (after a `mvn clean install` of course for updating connector in global repo).
