'How do I include the sat4j library in eclipse java IDE?

I've tried so many times to import the sat4j library (https://www.sat4j.org/index.php) into the java IDE eclipse by adding the jar files in the lib folder which came with the download of sat4j library (commons-beanutils.jar, commons-cli.jar, commons-logging.jar...). But somehow I always get the error message Invalid ZIP file for every jar file I tried to include and now I'm wondering if its even possible to include it in eclipse at all..
