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.

Answer 13

Adding custom JAR files to the EAR project

1. Copy the custom JAR to the root directory of the EAR project.
2. Define the JAR as a Utility JAR. Open the Java EE perspective. ...
3. Add the new JAR to the class path by adding it to the MANIFEST. MF file. ...
4. Republish the WebSphere Commerce application.

Contrary to what people have said here, you can put an external jar in a folder under your checked-out project directory and haven Maven find it like other dependencies. Here are two crucial steps: Use "mvn install:install-file" with -DlocalRepositoryPath. Configure a repository to point to that path in your POM
