Note : Here may be possible you will get the error like ‘@0.0.0.0:8080: java.net.BindException: Address already in use: bind‘. don’t worry, you are getting the above error because your port 8080 is busy by some other services. To resolve this issue, open the another command prompt and fire command ‘netstat -ano | find “8080” ‘ .
This will give you the processes which are using the port 8080. like –
