Can't import Xbee Java Library in Processing 3.1.1 (MacOS 10.5)

Hi,

I try to run the follow_the_leader demo from XBeeArduinoCodingPlatform (see https://docs.digi.com/display/XBeeArduinoCodingPlatform/Follow+the+Leader).

Unfortunately, I get : No library found for com.digi.xbee.api.models No library found for com.digi.xbee.api.connection Libraries must be installed in a folder named 'libraries' inside the 'sketchbook' folder.

However, I have put the XBJL-1.1.1 directory in the ~/Documents/Processing/libraries directory as required.

Could anyone help me ?

Thank you.
