Windows/Linux/Mac Eclipse plugin to compile and upload arduino sketches

Hello,

i just installed eclipse photon with the sloeber and i am trying to use some of my custom libraries but it doesn't seem that it can find them. I saw the directory that it uses to search for the libraries arduino/preferences and it is where i have placed my libraries. I saw another post with the same problem and i want to ask if with the 4.3 version this problem is going to change. I installed sloeber from Eclipse Marketplace, is it the 4.3 version or do i have to install the github that jantje uploaded recently? Also i want to use eclipse with teensy 3.6, any updates about the way i can achieve that, i' ve read the trippy lighting tutorial but it is for really old version of the software.

Thank you very much
