Opening of an asciidoc file outside workspace fails

[de-jcup]

Situation

I wanted to open an external asciidoc file wih File -> Open File ...

• The path wath something like this:
  `/home/developer/projects/sechub/sechub-doc/src/docs/asciidoc/documents/gen/gen_pds_executor_config_paramters.adoc
• The file exists

But... I got an exception (see below inside "details").

Workaround

Use a temporary project, add a File and use Advanced option to link to the external file.
Then open the linked file from workspace - works now.

Wanted

It shall be possible to use File -> Open File ... to open any asciidoc file with the editor

Solution

open
