I run the command

"netstat -aon | findstr "8080"

. But I find no process locking down that port. I also try to change the httpPort to some different port numbers like this in the build.gradle file, I still get the same error, inspite of using bizarre port numbers -

tomcatRunWar {
    httpPort = 8190
}

The port that is failing for you is the stop port. As you are not defining one it uses the default port: 8081. Try to change that one.

tomcatRunWar.stopPort = 8191

I am also facing the same problem… tried changing like that tomcatRunWar {

contextPath = “”

stopPort = 8191 } Caused by: java.net.BindException: Address already in use: JVM_Bind :8080
