Problem of compilation of Bluefruit : many versions of the library found...

I have a problem when I compile the Bluefruit library.

I don't understand why it suddenly doesn't compile.
The installation was ok and i compile the project since a while...

Plusieurs bibliothèque trouvées pour "bluefruit.h"
Utilisé : C:\Users\F085404\AppData\Local\Arduino15\packages\adafruit\hardware\nrf52\0.14.6\libraries\Bluefruit52Lib

Thanks for taking the time to post an update @Vincent25. I'm glad to hear you found the real error.

FYI, there is actually only one version of each library. Those "Plusieurs bibliothèque trouvées pour" messages are caused by a bug in Arduino IDE 1.8.10:

github.com/arduino/arduino-cli

Print "multiple libraries found for header.h..." only when it really happens

Previously printed: ``` Multiple libraries were found for "DHT.h" Used: /h…ome/megabug/Workspace/sketchbook-cores-beta/libraries/DHT_sensor_library Multiple libraries were found for "Adafruit_Sensor.h" Used: /home/megabug/Workspace/sketchbook-cores-beta/libraries/Adafruit_Unified_Sensor Using library DHT_sensor_library at version 1.3.8 in folder: /home/megabug/Workspace/sketchbook-cores-beta/libraries/DHT_sensor_library Using library Adafruit_Unified_Sensor at version 1.0.3 in folder: /home/megabug/Workspace/sketchbook-cores-beta/libraries/Adafruit_Unified_Sensor ``` Even if there are no multiple libraries available for the particular header. After this patch we have: ``` Using library DHT_sensor_library at version 1.3.8 in folder: /home/megabug/Workspace/sketchbook-cores-beta/libraries/DHT_sensor_library Using library Adafruit_Unified_Sensor at version 1.0.3 in folder: /home/megabug/Workspace/sketchbook-cores-beta/libraries/Adafruit_Unified_Sensor ```

That will be fixed in the Arduino IDE 1.8.11 release. Until then, please just ignore these messages. You'll know a legitimate "Plusieurs bibliothèque trouvées pour" message when it shows a "not used" path in addition to the "Utilisé" path.
