I need help fixing the "multiple libraries error" in the cloud editor (for Arduino IoT)

Using Arduino Programming Questions
1

This is the relevant code (in the cloud sketch):

#include <EEPROM.h>
#include <SPI.h>
#include <NRFLite.h>

#include "thingProperties.h"

I want to import theese libraries to use them to create a smart light system for myself.
The rest of the code already works great when I upload it via the normal IDE 2.0 but I want to use the IoT system including its dashboards to make accesing the lights easier!

This is the error message I've been getting for the last 3 days or so:

Multiple libraries were found for "EEPROM.h"
  Used: /home/builder/.arduino15/packages/esp8266/hardware/esp8266/2.5.0/libraries/EEPROM
  Not used: /home/builder/opt/libraries/atmac_eeprom_1_0_0

Multiple libraries were found for "SPI.h"
  Used: /home/builder/.arduino15/packages/esp8266/hardware/esp8266/2.5.0/libraries/SPI

Multiple libraries were found for "NRFLite.h"

  Not used: /home/builder/opt/libraries/nrflite_3_0_3
  Not used: /home/builder/opt/libraries/nrflite_3_0_2
Error during build: exit status 1

I've already read about this error and found some posts explaining I had to download the libs as .zip and change their names in the .properties file. I tried that and it did not work for me. No matter how I changed the name of the header file it just wouldn't import the correct version either.

Can someone explain this error in detail and suggest solutions? I am really out of ideas at this point!

Many Thanks,
Nico

First off, those are not errors, they are just informational messages telling you the compiler found multiple libraries and informing you which one is is using. Whatever your error is, it is probably further up screen in the part you didn't post.

You're right! I checked the console output again and found this error message:

I fixed it by changing the CD definition to CD2 and everything works fine now!
Thank you so much for your help!
