> If you search for Calcite on Maven Central [1] you will see that the latest version of the “calcite” and “calcite-examples” artifacts is 1.21, whereas the latest version of everything else is 1.22.
What is the purpose of "calcite" artifact? Was <dependency><group>org.apache.calcite</group><artifactId>calcite</artifactId></dependency> useful? A missing bit is the publishing of calcite-bom (bill-of-material). It would be helpful for the consumers so they get all the versions of -linq4j, -core, etc, by adding a single dependency on the bom artifact. Here's the bom for JUnit5: https://repo1.maven.org/maven2/org/junit/junit-bom/5.7.0-M1/junit-bom-5.7.0-M1.pom Vladimir
