Hi, I wonder where the pylint output file is stored when running

pants lint

. I notice that pants 2.9.0.dev2 uses pylint 2.11.0+, which supports

--output

option for generating report file. I have that specified as

[pylint].args = "--output=./pylint.report.txt"

in pants.toml. I observe that the output isn't printed on the console but, after the run, I can't find the generated report anywhere under the project root. Maybe I forgot to check somewhere else?

Py lint is invoked in a sandbox, that’s why you don’t see the file in your project. Try with

output=%(buildroot)s/report.txt

Normally we capture linter reports from the sandbox and copy them under

dist/

, but it looks like we don't do that for pylint

Thanks for explaining. Issue updated: https://github.com/pantsbuild/pants/issues/13686 Moreover, it seems pants keeps cancelling & rescheduling the linting process with

--output=%(buildroot)s/report.txt

. I'm getting the below output when running on osx. Not knowing the exact internals, I guess that the files in

buildroot

are being monitored by pants and writing pylint report file right there invalidates the linting process in some way, causing a new job to be rescheduled (and to be invalidated again). Specifying the report under "dist" directory seems to be a better choice.

Yeah, you will want to write it to a folder included in the option

[GLOBAL].pants_ignore

, list the

dist/

folder
