"PreLaunchTask" is not finished before the launching starts

[zhengbli]

I have a simple TypeScript project, and I need to generate sourcemap before debugging.
I have a tsc task that does the job, and I set it as the preLaunchTask field for my launching configuration. However, the launch seems to be starting before the sourcemaps finished generating.

I'm also seeing this. I believe it was working correctly in 0.9 but doesn't seem to be working correctly now.

Happens for me - the debugger seems to be launching before the pre-launch task completes. Was working fine in 0.9.

Yes I acknowledge the bug, happened because of a change in our task framework.

@dbaeumer now I wait for the task to finish if it is not a watching task. You can review it debugService.ts#592

[dbaeumer]

@isidorn makes sense. However you could even be smarter with watching tasks as well. You could add a listener for state changes on the task and the wait for the first 'inactive' event.

[isidorn]

But that can take forever and then I never launch debug, right?
I am a bit reluctant to add that.

[dbaeumer]

Yes that is true.

I'm experiencing same issue. In which version will be this fix? I'm on Version 0.10.3 / Commit 783ecf841a2b21edca6d86853670cae89b4c244f

[isidorn]

This will be fixed in the next stable version after 0.10.3

@isidorn Ok, thanks
