Error using YAML format

Hi, I'm using liquibase 3.5.4 on fedora 26, and I trying to use YAML format but I get this error in a update command:

I have the file "snakeyaml-1.17.jar" in the lib folder but it seems that is not read. I try to change permissions (read, execution...) but nothing change. In xml format works great.

With version 3.6.1 I have a similar error:

I also have the corrects files (logback-classic-1.2.3.jar, logback-core-1.2.3.jar, slf4j-api-1.7.25.jar, snakeyaml-1.18.jar) in the lib folder. In this version no command works.

Any idea? Thanks.
