Waiting for preLaunchTask 'build'...

[aol-nnov]

If I choose 'start debugging (run extension) in the newly generated extension, extension host does not actually start and the whole thing is in some "hang state". In a while "Waiting for preLaunchTask 'build'..." message appears.

Appeared that default build task depends on two watch tasks, and they, eventually never finish.

Quick googling revealed a problem, but the solution from that post did not help.

Changing preLaunchTask to a non-watch task (i.e.: npm: compile) helps, but increases startup time.

Also, it was mentioned earlier: #311

Appears to happen with esbuild bundler only

After encountering the same problem, it turns out the connor4312.esbuild-problem-matchers extension and the "problemMatcher": "$esbuild-watch" in the task definition is what makes this work.

Sadly the extension is not available on Open-VSX and the maintainer declined to publish it on Open-VSX (connor4312/esbuild-problem-matchers#6), so I had to build it myself for code-oss.

The extension only contains some problemMatcher definitions in the package.json, so it would be possible just to inline them into the tasks.json. But I guess it’s futile to ask for Open-VSX compatibility in a Microsoft repo.
