Oh. It means you miss dependencies (jar files) required to compile and execute the code. I suggest you import Calcite source code (e.g. as explained here: https://calcite.apache.org/docs/howto.html#setting-up-intellij-idea ) Then IDEA will see all the dependencies, and you will be able to execute examples. As you get familiar with the way Calcite feels, you might could create a standalone project that uses Calcite. Vladimir
