I’m having trouble making updates to BUILD files for python code. I’m adding a new project into a monorepo that already had pants configured for a basic project. I generated build files for the new code using pants tailor but any updates to build files are not reflecting. (Examples: changing the name in python_tests does not actually change the name, adding/removing/changing versions for requirements doesn’t reflect and instead pants continues to use the initial requirements file that was used). Has anyone run into this? Is there a command I’m missing after making changes to BUILD or a cache that needs to be cleared. I’m using pants 2.15 and python 3.8 with Ubuntu 20.04 on windows 10.

Pants’ file watching won’t work if your checkout is outside of your WSL session… could that be the issue?

I was editing using an IDE. But I just tried to make a change with vim in a separate Ubuntu window then run pants from the same window and it appears the same issue is occurring.

The key here is not where the ide / editor is located relative to the code, but where the source code itself is located. It must be inside the Ubuntu VM and not under C:\, etc.
