Describe the bug

Starting workspace with Apache Camel devfile (https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/apache-camel-springboot) takes really really long time to start language server. 13mins from my last experiment. It stays for long time on 57%, it looks like it gets stuck. I've tested also Spring petclinic (https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/java-web-spring) which takes over 3 minutes.

Che version

  • nightly

Steps to reproduce

  1. start workspace with Apache Camel devfile (https://github.com/eclipse/che-devfile-registry/tree/master/devfiles/apache-camel-springboot)
  2. open workspace and check bottom panel and wait

Expected behavior

Java Language Server should load maven project in real time

Runtime

  • minikube (include output of minikube version and kubectl version)

Screenshots

JLSload

Installation method

  • chectl

Environment

  • my computer
    • Linux

The same thing happens when opening the project https://github.com/jboss-fuse/fuse-rest-http-booster in VS Code.

It's just spending lots of time resolving all the dependencies.

@fbricon thanks. I'm happy with exposing what is happening to the UI as a solution for this issue. Once that's fixed, I would close this one as well.

Issues go stale after 180 days of inactivity. lifecycle/stale issues rot after an additional 7 days of inactivity and eventually close.

Mark the issue as fresh with /remove-lifecycle stale in a new comment.

If this issue is safe to close now please do so.

Moderators: Add lifecycle/frozen label to avoid stale mode.
