Existing file not resolved via XML Catalog

[daliboris]

Hello,
I set up multiple XML catalog files and turned on all messages from resolving resources (see following image):

oxygen27.1_2025-07-12T14-23-35.png

When editing an XProc 3.1 file, I get the following error:

Code: Select all

Could not resolve URI: [file:/V:/Projekty/Github/Daliboris/XProc/xproc-framework-for-oxygen/src/schemas/3.1/rng/xproc31.rng]

The problem is that this file exists, is valid and I can open it in the oXygen XML Editor.

Why does this error occur?
