Go to File-  Project Structure-  Libraries and click green     to add the directory folder that has the JARs to CLASSPATH  Everything in that folder will be added to CLASSPATH   Update    It s 2018   It s a better idea to use a dependency manager like Maven and externalize your dependencies   Don t add JAR files to your project in a  lib folder anymore

If  as I just encountered  you happen to have a jar file listed in the Project Structures- Libraries that is not in your classpath  the correct answer can be found by following the link given by  CrazyCoder above  Look here http   www jetbrains com idea webhelp configuring-module-dependencies-and-libraries html  This says that to add the jar file as a module dependency within the Project Structure dialog    Open Project Structure Select Modules  then click on the module for which you want the dependency Choose the Dependencies tab Click the     at the bottom of the page and choose the appropriate way to connect to the library file  If the jar file is already listed in Libraries  then select  Library

On the Mac version I was getting the error when trying to run JSON-Clojure json clj  which is the script to export a database table to JSON  To get it to work I had to download the latest Clojure JAR from http   clojure org  and then right-click on PHPStorm app in the Finder and  Show Package Contents   Then go to Contents in there  Then open the lib folder  and see a bunch of  jar files  Copy the clojure-1 8 0 jar file from the unzipped archive I downloaded from clojure org into the aforementioned lib folder inside the PHPStorm app Contents lib  Restart the app  Now it freaking works    EDIT  You also have to put the JSR-223 script engine into PHPStorm app Contents lib  It can be built from https   github com ato clojure-jsr223 or downloaded from https   www dropbox com s jg7s0c41t5ceu7o clojure-jsr223-1 5 1 jar dl 0
