Re: [keycloak-user] Attempting to build authenticator example and failing.

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 (default-cli) on project authenticator-required-action-example: Failed to execute goal deploy: {"WFLYCTL0062: Composite operation failed and was rolled back.
