[Feature] Including build failure log in main output

[KishanBagaria]

We're building native deps on GitHub Actions. When build failures occur, yarn saves the log to a build.log file in a random location. Only way for us to see the log is to upload C:\Users\RUNNER~1\AppData\Local\Temp\xfs-*\build.log as CI artifacts.

  ➤ YN0009: │ foo@https://github.com/bar/foo.git#commit=hash couldn't be built successfully (exit code 1, logs can be found here: C:\Users\RUNNER~1\AppData\Local\Temp\xfs-150f75fd\build.log)
515

Is it possible to include build.log in the main log (process.stdout) instead of saving to a new file?

Edit: overlooked the logs at the top

How was this problem fixed? It's still a thing today (I can't find any option to configure where the logs are placed, at least that would allow us to upload it as an artifact for later inspection, but the current randomised path makes it almost impossible).

In CI environments, the enableInlineBuilds config defaults to true, which means ALL builds outputs (not only failing ones) are written to stdout with a prefix

It's never worked in Google Cloud Build. We have to pass --inline-builds to yarn install. However, that argument does not work for yarn workspaces focus.

Looks like that will be fixed in the next release via #6377

Anyway, you can force CI to be detected by setting environment variable CI='true'. Alternatively, you can directly set the value of enableInlineBuilds via yarn config set enableInlineBuilds true or setting environment variable YARN_ENABLE_INLINE_BUILDS='true'. Both of those should work for all installs, including yarn workspaces focus.

Also, this popped into my notifications earlier (that's why I commented in the first place) but nothing happened to trigger that notification? Strange

@clemyan That's really great to know, we will try that. Thank you. 👍
