Qt Creator currently doesn't warn you when an artifact couldn't be updated due to another process still being open. This happens often when you're in the run/test cycle:
- Open e.g. Qt Creator, Run it
- Fix something in some plugin
This will print
"The process cannot access the file because it is being used by another process."
in Compilation output, but nothing more. Creator doesn't list this under the Tasks, and will run the new instance quite happily.
What I'd expect: Creator filtering for this output, and marking the build as a failure.
