Exclude .pio directory from Check when MISRA addon enabled

PlatformIO Core
1

Hi,
I want exclude .pio library from Cppcheck but neither check_patterns nor pio check --pattern works.
My Ploatformio.ini

[env:desktop]
platform = native
build_flags = -std=gnu++11 -Iinclude -Ilib -DDEBUG -DUNIT_TEST
test_build_project_src = yes
test_transport = custom
test_ignore = test_embedded
lib_deps =
fabiobatsilva/ArduinoFake@^0.2.2
noah1510/Native SPI@^0.1.0
check_tool = cppcheck
check_flags = --enable=all
cppcheck: --addon=misra.json
check_severity = medium, high
check_patterns = src/*.*

Can you give a minimal code examoke too that shows in which way exactly it’s not working?

Yes, instead of excluding .pio directory, it check the content of .pio directory.

In platformio.ini I use

[env]
check_tool = cppcheck
check_flags = --enable=all
check_src_filters = 
    +<src/*>
    +<lib/*>
    -<lib/TFT_eSPI/*>
    -<.pio/*>
    +<test/test_*/*>

But still it’s doing cppcheck on all external libraries in .pio/libdeps
I don’t want it to run cppcheck on others people code but rather focus on my own code.

Example of output because I use ArduionoJson…
