The zip and the tar.gz files are our windows and linux/mac distributions. This binary release does not contain FirstSpirit api jars (fs-access.jar or fs-isolated-runtime.jar). Please add either of them to lib directory. Since version 2.2 FSDevTools requires at least FirstSpirit Version 2018-11. The fsdevtools-cli-x.x.xxx.jar file can be used to compile against (Keep in mind that you should rather clone this repo and install all submodules to your local Maven repo).
