The application already exists in the websphere configuration library, exception handling
One of the reasons for this problem: the uninstallation is not completed on the operation interface.
Do this:
1. Delete the corresponding folder under $WAS_HOME/profiles/AppSrv01/config/cells/...cell/applications
2. Delete the corresponding folder under $WAS_HOME/profiles/AppSrv01/installedApps/...cell
If there is still a problem, please restart websphere.
Forcible method, find relevant delete all
find . -name 'project name*'|xargs rm -rf
This is the solution that is usually found on the Internet, but maybe after you delete the application file, the deployment problem still occurs. You can try to log out of the user and log in again .
The deployment is successful, I hope it helps you!
