OK - I'm running now in debug mode. My intent is to add and test a "hello
world" plugin to prove everything is wired up and that I can debug all the
way into the plugin I wrote...
I want to test plugins/addons which, as I understand it go here if you're
adding them to an installed version of Solr.
solr-6.x.x/server/solr-webapp/webapp/WEB-INF/lib/
So - to get that all working (build and seeing source when in debug mode)...
1. Where, exactly, should I place the source code for a new plugin that is
NOT a part of the Solr distribution if I want to be able to debug through
that code as well? (I understand that the appropriate entries will need to
be in the correct xml files in the core/collection configurations)
2. Will I need to change the build.xml files in some way? If yes, please
tell me how, I'm unfamiliar with Ant.
3. In case I'm in "X/Y problem mode" here - My goal is: Add plugin source
code, build, make config changes where needed, and see source when I put a
breakpoint in code.
