Why can't it find the package?

Question

Java

Hello. Gives an error when trying to include a .jar file.

javac App.java
java -cp .:libs/mysql-connector-java-5.1.32-bin.jar:libs/Rootbeer-1.2.0.jar App

App.java:5: error: package org.trifort.rootbeer.runtime does not exist
The package exists, opened it with the archive manager and looked at the path. What could be wrong?
Directory structure with base class
java
-App.java
-libs

It seems to me that in your Rootbeer.jar there are not compiled files (.class), but source codes (.java)
