  1. Click File from the toolbar
  2. Project Structure (CTRL + SHIFT + ALT + S on Windows/Linux, ⌘ + ; on Mac OS X)
  3. Select Modules at the left panel
  4. Dependencies tab
  5. '+' → JARs or directories

You can add a jar file in Eclipse by: 
right-clicking on the Project → Build Path → Configure Build Path. 
Under Libraries tab, click Add Jars or Add External JARs and give the Jar.

Simple as that.

The best way is to add the jar to your project is as follows:

  1. Create a folder called lib in your project folder.

  2. copy all the jar files you need to this folder .

  3. Refresh your project in eclipse.

  4. Select all the jar files, then right click on one of them and select Build Path -> Add to Build Path

Right click on your project and choose Build Path -> Add Library

Then configure the build path and you are good to go.

You can also create a "lib" folder in the root of your project. Put you jar library in.

And then boot up intellij, right click on your java, and select "Use as library".

Just did this to my own project.

Another approach could be:

Launch IntelliJ IDEA. If the Welcome screen opens, press Ctrl+Shift+A , type project from existing sources , and click the Import project from existing sources action in the popup. Otherwise, from the main menu, select File | New | Project from Existing Sources.

IntelliJ IDEA 15 & 2016

  1. File > Project Structure... or press Ctrl + Alt + Shift + S.
  2. Project Settings > Modules > Dependencies > "+" sign > JARs or directories...
  3. Select the jar file and click on OK, then click on another OK button to confirm.
  4. You can view the jar file in the "External Libraries" folder.
