$ dart --version
Dart VM version: 2.0.0-dev.64.1 (Thu Jun 21 08:47:55 2018 +0200) on "linux_x64"

Cron executed build job failed this morning with many errors like this:

Failed to precompile build_runner:graph_inspector:

FYI, I was seeing that error too this morning, but updating some package versions made it go away. Try updating to build_runner: ^0.8.10.

(You might want to update to test 1.0.0 while you are there.)

seeing this error on a lower sdk dev.60 as well just FYI

[anders-sandholm]

Just wondering, did updating to a later build_runner version help resolve the issue, @pulyaevskiy ?

[pulyaevskiy]

@anders-sandholm , thanks for checking in!

Yes, looks like upgrading to latest versions of everything seems to have solved the issue (I suspect main culprit in my deps was outdated analyzer version which was using older front_end package).

I'm still going through some new strong mode fixes, but dependencies are resolved without issues now: https://travis-ci.org/pulyaevskiy/node-interop/builds/395544708

Thanks @chalin for help!

[natebosch]

Thanks for confirming.

Run pub upgrade and trying again. (You might also need to rerun pub global activate foo for the foo commands that you use (such as webdev and/or stagehand). If that doesn't help, then we'll need more info.

[nyvelius]

@chalin D'oh. So yeah, pub upgrade and not just pub get...

[MikeMitterer]

pub upgrade didn't help in my case. I had to change dev_dependencies from build_runner: ^0.8.0 to build_runner: ^0.9.0 - this helped

[thosakwe]

Hm, also getting this, error. I have 2.0.0-dev.65.0, as well as build_runner@^0.9.0.

Some relevant info from my lockfile:
