Ok. I see. The error in your PR is exactly the same. I guess it was caused by https://github.com/apache/calcite/commit/bcac62e3dad6137511d4451135daa2d1762ec6ad#diff-c25007f5834d66d28e0b6644edf21325L55-R69 In other words, `master` branch build was broken, and PR is validated by merging with master branch. I've fixed master branch, so CI in your PR would likely work. Vladimir
