"$ENV{IDF_PATH}/components/esp-homekit-sdk/components/homekit"

am alredy using the apple home kit in my ESP-IDF project

now i want to add the

"${ESP_MATTER_PATH}/components"
"${ESP_MATTER_PATH}/examples/common"
"${MATTER_SDK_PATH}/config/esp32/components"
${extra_components_dirs_append}

matter protocol in the project

when i head to add this

CMake Error at /home/dharanesh/esp/esp-idf/tools/cmake/component.cmake:251 (message):
ERROR: Cannot process component requirements. Multiple candidates to
satisfy project requirements:

requirement: "json_generator" candidates: "espressif__json_generator, json_generator"

i got this error how to resolve it

and this is my components CmakeLists.txt

[shubhamdp]

@0xdharanesh can you please provide a few more information

esp-idf commit id
esp-homekit-sdk commit id
esp-matter commit id

[0xdharanesh]

@shubhamdp

I had already fixed the issue in a similar way before receiving your message, but I waited for your response to confirm or to see if there was a better way to resolve it.

I manually deleted the json-generator-and-parser and also Modify them on SDK's idf_component.yml. After that, everything worked well.

Here are the details:

esp-idf commit ID: cc3203dc4f087ab41b434afff1ed7520c6d90993
esp-homekit-sdk commit ID: 43bab6f68569e26c738f0273960200c809ec0ec9
esp-matter commit ID: a4739ac
All of these were the latest stable versions i think.

Thank you for your help, @shubhamdp !

[shubhamdp]

@0xdharanesh working on fixing it, but it may take some time, as this needs to be supported on prior IDF versions as well.

[0xdharanesh]

@shubhamdp okey

[shubhamdp]

@0xdharanesh can you try please with the attached patch?

fix-homekit-and-multiple-components.patch

[dhrishi]

@0xdharanesh Any update you can share? Please close the issue if this works

[0xdharanesh]

I had already fixed the issue in a similar way before receiving your message, but I waited for your response to confirm or to see if there was a better way to resolve it.

Because i have planed to create a virtual bridge
from this SDK i can't figure it out if it work with google but not with alexa in homekit its have many issues so i am developing with bridge-app/esp32

thanks @shubhamdp @dhrishi
