May I ask why you prefer to install v1 over v2 ?
Using v2 would be the first step of migration to OH3 as v1 is not available for OH3.
The error message has a strange spelling
is this copied from the original error message or did you type it manually ?
Is there anything else behind this error message like a hint that mvn access does not work ?
If yes this should help: openHAB 2.5.x and the sunset of Bintray
