Current the run and start goals will override a downloaded and uncompressed version of WildFly if the jboss-home configuration parameter is not defined. The contents are put in ${project.build.directory}/wildfly-run. What should happen is the archive should be extracted to the ${project.build.directory} directory, e.g. for org.wildfly:wildfly-dist:14.0.1.Final:zip the path should be ${project.build.directory}/wildfly-14.0.1.Final.

This will also be useful for WFMP-62 where the start goal might be executed followed by execute-commands to configure a server for tests.
