I want to add/modify solr code (e.g. Adding new plugin/Stream Decorator)

Is there any documentation which describes how to create a new
plugin/Stream Decorator?
I don't think there is. Your best option is to examine code in Solr or
Lucene for existing classes of the same sort of plugin you want to
create and use that as a template for your plugin. What kind of plugin
did you want to write? There are a lot of possibilities. Somebody here
can figure out what class to use for inspiration. If you are wanting to
do a stream decorator (your question includes that) then I have no idea
what class in Solr you would want to use as astarting point. I can't
find any examples when I search the codebase, so apparently I do not
know what to search for.
As for the way to build a project for the plugin, use your favorite Java
project building mechanism and have it add solr-core as a compile
dependency, but not a build dependency. I generally use
https://start.spring.io to build a new project and import that into
eclipse. The nice thing about that is that when you compile it, you'll
get two jars ... one with just your code and one with all the
dependencies included. You would most likely want to use the one with
just your code. It's a bad idea for a plugin to include any classes
already loaded into Solr. That tends to cause problems, even if those
classes are identical to what Solr already has.
