Error Starting JBOSS EAP, Service is already registered

Got a weird error today when deploying a new war to an existing jboss eap environment, it is said that my url is already registered. Here is the complete stacktrace,

2017-10-24 18:47:49,721 ERROR [org.jboss.as.controller.management-operation] (External Management Request Threads -- 1) WFLYCTL0013: Operation ("add") failed - address: ([("deployment" => "my-local-1.0.0-20171024.1141.war")]) - failure description: {

}

    "WFLYCTL0180: Services with missing/unavailable dependencies" => undefined
}

The error is actually located on my jboss-web.xml, im deploying 2 war files which have the same context-root url. Changing the deployed war’s context url solve this problem.

<jboss-web>
    <context-root>/</context-root>
</jboss-web>

Wildfly is already running when you try to start it. Check your process viewer, it may show up as wildfly it may show up just as 'java'. You could be running it as a service, you could be running it from the command line, it is possible that Eclipse started it and isn't aware of it any longer.
