How to add jar files in IntelliJ?

I'm new to IntelliJ and I've been trying to figure out how to add a jar to an existing project.

In my project, there is an example project, which was created using the wizard. In this project, the jars from the example project are added in the lib folder, so I can run the example.

So I copied the example project's .idea folder to my project, and I wanted to add the jars of the example project to my project. But I don't know how to do it, so I tried the following methods:
1) I created a new class in my project, and put the jars in the lib folder. I then modified my build.gradle file as below, and I tried to run my project. I got the error below:
Java.lang.NoClassDefFoundError: org/apache/commons/collections/CollectionUtils
2) I didn't create any new class, but I just copied the jars in the lib folder. So I modified the build.gradle as below, and I tried to run my project. I got the error below:
Exception in thread "main" java.NoClassDefFoundError: org/apache/commons/collections/CollectionUtils at com.demo.run(JarMain.java:12)

How to install Selenium server jar?

I am working on a web application where the client is asking for a selenium jar file to be installed on the local machine for the automation.

I have installed Selenium jars for java and .net on my local machine, but I don't know ?

You can install Selenium server in 3 ways. Download the Selenium server jar from here. Create a Java project. Extract the jar file into that project folder, make sure it has the package selenium-server. Run the application. Simply download the selenium-server-standalone-3.0.1.jar from and copy it to your project directory. Then add that jar to the build path of your project.

The simplest way is to install the "install4j" software that allows you to create an "installer" for your . Then simply click the button "add executable". This will create an exe file which you can run to install the jar.
