OH1 Binding Debug

Hi all,
I am trying to debug a binding in order to fix some bugs.
I am not familiar with Java but have familiarity with other languages, so shouldn’t be too difficult.

In order to debug an OH1 binding what should I be doing?
I have the OpenHAB 1 core running on Raspberry Pi and the Eclipse on a Windows 10 PC.
I have read the (short) IDE instructions written by Kay, but they seem to me for OH2, and they are not very clear anyway.

Any help will be appreciated…
