Alfresco v23 - signing PDF documents - Problem during building phase

[darkokrstevski-kontego]

Hi,

I have Alfresco 23.2 in place and what to deploy add-on or module to sign PDF documents.

I tried to build modules (sudo mvn clean install) however, I got the following error:
...
[INFO] afirma-crypto-pdf 1.9-SNAPSHOT ..................... FAILURE [ 0.021 s]
...
[ERROR] Failed to execute goal on project afirma-crypto-pdf: Could not resolve dependencies for project es.gob.afirma:afirma-crypto-pdf:jar:1.9-SNAPSHOT: Could not find artifact es.gob.afirma.lib:afirma-lib-itext:jar:1.0.6-SNAPSHOT -> [Help 1]

Could you please, point out what steps to do in order to fix the issue?

Kind Regards, Darko
