I don’t understand what you mean by “two party Library”. If you want to change the parser, and those changes do not go into the core parser, then you will need to make your own jar file. There is an example of this in core/src/test/java/org/apache/calcite/sql/parser/parserextensiontesting/ExtensionSqlParserTest.java added in https://issues.apache.org/jira/browse/CALCITE-1384 <https://issues.apache.org/jira/browse/CALCITE-1384>.
