WSO2应用程序服务器CarbonAppUploader将不会覆盖现有工件

Question

I am trying to use CarbonAppUploader to deploy a carbon application on WSO2 Application Server. The service deploys the app as per log, but then complains if an artifact already exists. See below:

TID: [0] [AS] [2014-01-14 15:14:52,496] ERROR {org.wso2.carbon.application.deployer.CappAxis2Deployer} -  Error while deploying carbon application /...skip.../wso2as-5.1.0/repository/carbonapps/0/MY_ARTIFACT-1.0.1-SNAPSHOT.car {org.wso2.carbon.application.deployer.CappAxis2Deployer}
java.lang.Exception: Carbon Application : MY_ARTIFACT already exists. Two applications can't have the same Id. Deployment aborted.

Answer 1

Please check whether you have deployed another CAR file with the same name but a different version. This error is thrown when you have 2 CAR files with same artifact name which is MY_ARTIFACT in this case but with different versions.

Please note that WSO2 Carbon Servers still do not have the multiple CAR file versioning.

Thanks and Regards,
