Hi, Calcite has a runtime dependency on org.pentaho:pentaho-aggdesigner-algorithm:5.1.5-jhyde
Juilan, Can you please clarify what is the source of that artifact? Is it actually safe under Apache 2 license? pentaho-aggdesigner is clearly GPL-2 licensed: https://github.com/pentaho/pentaho-aggdesigner/blob/master/pentaho-aggdesigner-core/gpl-2.0.txt I am not an expert in licensing issues, however I think it is not valid to change project license from GPL to whatever by merely performing a fork (https://github.com/julianhyde/pentaho-aggdesigner/commit/c9dd9a057ec5a74eefeee63b3a519aa26c7733e2). It looks like we should either drop pentaho-aggdesigner dependency, or convince pentaho to enable Apache 2 compatible usage of the artifact in question. -- Regards, Vladimir Sitnikov
