title: IntelliJ IDEA: Include external library in production directory
body: <p>I am using IntelliJ IDEA to develop a Java project. To include the mysql-connector-java library I use, I created a folder named lib in the root of the project and added the JAR to it. After that I added it as a global library using the context menu.
  When debugging it, everything is working fine. But when I navigate to the production directory and try to run it from the command line it cannot find the library. How can I include it in the production directory to allow accessing it when running my main class? Or is there another way to get this done? I just want to make sure, that all external libraries my project is depending on are properly included.</p>
