####Jenkins Deployment Plugin with support for JBoss 6.x, 7.x and WildFly 8.x####
To use JBoss 7.x and WildFly 8.x support you have to manually upgrade the log4j library in your jenkins.war. This is required because jboss-logging depends on a newer version of log4j.
Open your jenkins.war with 7z and replace the log4j-1.2.9.jar in *\WEB-INF\lib* with the latest version log4j-1.2.17.jar.
