Build of extension using "mvn clean package" produced unusable result

[SundialServices]

When following the instructions on this web page, the latest (2.3.3) server would not start at all. Prior versions of the server would not successfully execute the extension (and indeed would not see that it exists). The server seemed to think that there were no "provider classes."

The only thing that did work was to install the binary distribution and to install it specifically onto neo4j version 2.3.1, which is no longer the most-recent one.
