It has to do with the dependencies. When I am running the sample code with changes as Test in ../calcite-master/example/csv/src/test/java/org/apache/calcite/test/ I have no errors. However, when I try to create my own project in Eclipse and after I have imported everything with maven repositories (from calcite 1.8 version and as external .jar the calcite-example-csv-1.9.0-SNAPSHOT.jar from the github version) the same error occurs :
