I can definitely sympathize with Tee's situation. In the latest release of
geotools (14.1) there are 223 different jar files. Chances are you don't need
all of them for your project. In fact, if you're a noob and load all the jar
files into a project without maven you'll get all sorts of errors.
Personally, I like my projects to have as small a footprint as possible with a
minimal set of jars/dependencies. In the case of geotools, that means removing
as many jars as necessary. I don't use maven so I have to prune the jars
manually.
First, I separate out all the jars into categories (raster/image jars, database
jars, vector jars, ogc/web related jars, xml/schema, commons, etc). Then I
start adding the jars I think I need and add more jars as needed. This is an
time consuming process but it keeps my final deployment size to a minimum.
Again, I don't use Maven and I don't know if it would help with this process.
However, it would definitely help folks like me if the jars could be binned in
some way. I can draft a list of bins if the packaging folks are willing to
entertain this idea.
Thanks,
Peter
PS. Love geotools! Thanks for everyone's hard work.

Subject: Re: [Geotools-gt2-users] embedding GeoTools is always a pain We are
starting to look at replacing JAI, and will be doing design and fundraising
over the course of 2016. JAI is not open source so we are unable to place it on
maven central. The second part is service provider interface is a pain in some
environments, and the "service registry" we use looks to be unsupported in Java

Dear GeoTools users and developers,
after embedding GeoTools in my n-th project I am very annoyed about the
complexity and pitfalls of this process. Two Scenarios to describe the
problem:
First: I wanted to parse a KML file and try to follow the Geometry Guide on
http://docs.geotools.org/stable/userguide/library/xml/geometry.html#kml-parser
1. add boundless repository and include gt-api, gt-main and gt-epsg-hsql
because I learned my lessons from projects before
2. trying to resolve the KMLConfiguration
a) adding gt-xml and gt-geometry modules as dependencies which is not
documented but seems to be meaningful because the how-to is about this
b) adding the xsd/gt-xsd-kml module as dependencies because I stumbled into
the xsd folder and it sounds meaningful as well
--> lucky me: it was the right one
Sidenote: I needed to scroll through the boundless repository manually to
scan for this modules
Second Scenario: whenever I want to do something with grid files - the JAI
library is required but not hosted in the maven central or boundless repo.
So I must use another repository (osgeo/webda) which seems to be the last
one which is hosting the JAI library :)
At the end of the day all this searching and trying needs a lot of time, is
not a pleasure and from my point of view not state-of-the-art because all
other libraries are available at maven central and are able to manage their
own dependencies. But in case of GeoTools I always need to look into
reference projects to find out how I was getting it the last time.
What are your experience with scenarios like this? Are you adding all
modules into the pom to not run into problems I always got or is there a
how-to I missed? :)
Thanks and kind regards,
Tee
