There is a step-by-step walkthrough on how to add user libraries in Eclipse at:
http://tutoringcenter.cs.usfca.edu/resources/adding-user-libraries-in-eclipse.html
Do NOT directly add a jar file to your build path. That will only work on your system for that specific project, and will not work for imported lecture code nor will it work for your project on other systems.
It is also important that you name your user libraries the same as the instructor. Otherwise, you may run into issues when importing Eclipse Java Projects from Github. Below are the names and links to the user libraries we will be using in this semester:
| Library | Eclipse Name | Download | Notes |
|---|---|---|---|
| Apache OpenNLP | opennlp-tools |
Link | You need to add the opennlp-tools-1.9.x.jar in Eclipse. You do not need the other JAR files. |
| Apache Log4j 2 | log4j2 |
Link | You need to add the log4j-api-2.x.x.jar and log4j-core-2.x.x.jar JAR files in Eclipse. You do not need the other JAR files, but you can use the appropriate *-javadoc.jar files to access the Log4j2 JavaDoc within Eclipse. |
Replace the x version numbers with the latest available versions.
This list will be updated over time.
