please help me.

I dont think Xampp supports Maven. Due to Wikipedia you need "Apache Maven for executing IntelliJ IDEA. Unfortunately i cannot help any further, as i dont know IntelliJ IDEA neither Apache Maven, but surely i can say that Xampp does not deliver Apache Maven.

Thanks for the reply but we did at the university. Now I can't do it my PC.

Why dont you try to install Apache Maven? See https://maven.apache.org

Thanks. I installed it but still above problem.

The problem is, installing and running a webserver is a quite sophisticated task. Its not as simple as installing a game or so. Usually educated system administrators are doing that job. It requires lots of knowledge about TCPIP, HTTP, Java JRE etc. etc. etc. - you cannot simply click a button and everything is fine.

Ask in your university for support. They really should know what is needed and how to configure it.
