Critical Description
Maven central now requires https. There are a lot of http://repo1.maven.org/maven2/ spread throughout the configs and codebase, and they are almost impossible to get rid of. Even if I update the config files and force it into the interpreter menus, it looks like the http version keeps coming in from some compiled code and prevents dependencies from downloading.
