How to connect a library to a project in Intellij IDEA?

Question

Java

I'm trying to connect the https://github.com/sirthias/parboiled library to my project. In Project Structure -> Module -> Dependencies I specify the path to the source code of the library.
But the idea still does not see the library classes, what should I do?

Answer 1

Classes need to be added, not source code. There is a link on the project page where you can get jar archives with them. Or just create a maven project.

Answer 2

In your case, if you are not using the build system (Maven, etc), download the JAR file:
parboiled-java-1.1.4
then its dependencies:
asm-all-4.1
parboiled-core-1.1.4
In Intellj Idea, open Project Settings and in the Libraries tab, add these JAR files to the project.
