Chao Wang created WFCORE-495: -------------------------------- 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 Assignee: 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. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
