Changing a package filled with.java files or a .java file to another package and the imports/package dir update automatically

I use IntelliJ. I would like to reorganize my packages and  files. I want to move whole files and packages without manually changing the imports and dir. Is there an easy way to do this? I notice that other mods almost never update their folder locations maybe because it's not yet possible? Do I have to install a plugin or IntelliJ?
