Step 1: Are you in the right place?

[x] I have verified there are no duplicate active or recent bugs, questions, or requests
[x] I have verified that I am using the latest version of the plugin.

Step 2: Describe your environment

Plugin version: 0.10.6
PyCharm/IDEA version: 2019.2.4
Mypy version: 0.740

Step 3: Describe the problem:

Steps to reproduce:

create new package
add foo.py with no annotations
add foo.py with annotations

Observed Results:

When running mypy from terminal with -p flag all of the package passes
When running from mypy-pycharm missing annotation errors are thrown.

Expected Results:

Stub files should be used when running the type check.

I'm fairly new to mypy and to the plugin. This might just be something that I'm doing inccorectly

You can see how the command that this plugin is constructed here: https://github.com/leinardi/mypy-pycharm/blob/b37d3b2fcdb5b819f383a5a77ebdfbe18f6f686c/src/main/java/com/leinardi/pycharm/mypy/mpapi/MypyRunner.java#L269-L301

Generally, it will run this: mypy --show-column-numbers --follow-imports silent <files separated by spaces> (and might also include a config flag). If you run this command in your situation, does mypy pick up the pyi? If not, try passing the pyi file as well. Curious about the results. Shouldn't be hard to solve this one.

What exactly was the resolution here?

I am encountering this issue because:

If file.py and file.pyi is passed it gives error of Duplicate module name
When I navigate the non-stub file, it is full of error because if you pass only that file it has no typing
When running without any input (all files) mypy is happy because the stub files are used

Maybe a solution for this is that if both .pyi and .py are present, do not run the plugin on the .py file. Would be a nightmare to figure out if it's a namespace package though. The most compatible solution would be to check the fullyqualified module name and run mypy -m
