Binding Development with Eclipse error message: bnd error: Illegal char

Development Add-ons
1

Hello dear openHAB community,

I’m new in developing bindings. After following the Developer Guide for developing Bindings in Eclipse and writing some code I get this error message and don’t know where it’s from. Can somebody help me with the following error? I have no clue what this means.

My pom.xml looks like this

The error message I get, when I hover over parent is:

Before trying to find the error you might want to update your sources to the latest code base. The version in your screenshot is 2.5.0-SNAPSHOT. That’s very old. So please make sure you branch is up-to-date with the latest 2.5.x version (or 3.x if you want to develop for the new version).

When I downloaded the latest 2.5.x snapshot (2.5.12) and tried it, I ran into this problem: Can't find binding skeleton script
So I should better use version 3 for developing bindings, I think.

For 3.x (3.1.0) I get yet another error. I opened a new topic to describe it: Getting started with Development openHAB 3 - Why can't I access paperui?
