             Summary: WFLY won't startup due to "WFLYCTL0212: Duplicate resource [(\"deployment\" => \"xxx.war\")]"
                 Key: WFCORE-495
                 URL: https://issues.jboss.org/browse/WFCORE-495
             Project: WildFly Core
          Issue Type: Bug
          Components: Server
    Affects Versions: 1.0.0.Alpha15
            Reporter: Chao Wang

WFLY won't startup due to "WFLYCTL0212: Duplicate resource [(\"deployment\" => \"xxx.war\")]"

If you firstly deploy a .war application by CLI command, then deploy 2nd time same .war application by copying it to /depolyment directory. After server restart, it shows:
{noformat}
15:26:26,913 INFO  [org.jboss.as] (MSC service thread 1-8) WFLYSRV0049: WildFly Full 9.0.0.Alpha2-SNAPSHOT (WildFly Core 1.0.0.Alpha15) starting
15:26:27,133 ERROR [org.jboss.as.controller.management-operation] (Controller Boot Thread) WFLYCTL0013: Operation ("add") failed - address: ([("deployment" => "xxx.war")]) - failure description: "WFLYCTL0212: Duplicate resource [(\"deployment\" => \"xxx.war\")]"
15:26:27,136 FATAL [org.jboss.as.server] (Controller Boot Thread) WFLYSRV0056: Server boot has failed in an unrecoverable manner; exiting. See previous messages for details.
15:26:27,138 INFO  [org.jboss.as.server] (Thread-2) WFLYSRV0220: Server shutdown has been requested.
15:26:27,153 INFO  [org.jboss.as] (MSC service thread 1-1) WFLYSRV0050: WildFly Full 9.0.0.Alpha2-SNAPSHOT (WildFly Core 1.0.0.Alpha15) stopped in 4ms
{noformat}

steps to reproduce:

1. start wildfly and deploy a .war application by CLI.
2. copy same .war application to /deployment directory
3. restart wildfly to see the error message. 

This happens because step 2 does a "full-replace-deployment" operation which does not remove content from standalone/data/content/aa/2d0425dd53572294d591b56efdee2680539eaf/content and deployment info from configuration file(standalone.xml). Therefore, you will have xxx.war in standalone/data/content and configuration file(standalone.xml), also a xxx.war and xxx.war.deployed file inside /standalone/deployments. A second time server restart will cause a duplicate resource error.
