I could run the Quickstart application
<https://docs.geotools.org/latest/userguide/tutorial/quickstart/maven.html>
without using Maven. My purpose was to get an understanding of what was
going on.
Maven's dependency tree shows 97 modules for this application. However,
with only 22 ones out of these 97 modules, the application could be run
perfectly without any issue. So 75 modules seemed to be not-required. Among
them, there were 37 modules from *it.geosolutions*, 12 modules from
*org.geotools*, 7 modules from *com.google*, and many other unnecessary
modules.
It would be appreciated if you clarify this for me.
