Circe is the new JSON library we added in 3.0. If you simply download the JAR from maven central, it typically does not include dependencies. So, either use a build tool like Maven or SBT, manually download required dependencies, or get the dependencies JAR from our release https://github.com/helgeho/ArchiveSpark/releases/tag/v.3.0
