@rafaeltuelho thanks for the report. Do you have any steps to reproduce? A specific file with which it occurs for instance?

[rafaeltuelho]

@apupier This seems to happen on a non-camel Java Project.
I'm not working with Camel at the moment. But when I open a Maven Java project I start to see annoying errors coming from Apache Camel Extension on my VSCode.
Not sure If it's reproducible. I can share the whole log message if you will.

[apupier]

I can share the whole log message if you will.

yes, please

[apupier]

I can share the whole log message if you will.

hum ok, no need. I understood the issue. Will provide a fix soon

[apupier]

@rafaeltuelho awaiting for the next release, you can pick a snapshot containing the fix: https://download.jboss.org/jbosstools/vscode/snapshots/vscode-apache-camel/vscode-apache-camel-0.0.29-49.vsix

(no planned date for next release, unfortunately current days priorities are fighting to migrate to another CI)

fix is available on released version 0.0.29
