6:12 p.m.
I downloaded Keycloak version 2.5.1 example file. Extracted it onto a CentOS 7 machine,
and installed Java-1.8.0 and java-devel.
When I attempted to use the example file: /examples/providers/authenticator
By typing: mvn clean install wildfly:deploy
I got the following error on the terminal where I was executing mvn:
ERROR] Failed to execute goal org.wildfly.plugins:wildfly-maven-plugin:1.1.0.Beta1:deploy
