Depending on what I'm doing, I need these processes either run alongside the project while I'm working on it (like watching source files), execute them automatically when something happens (like setting up a Stripe webhook proxy when I start the debug build), start them with environment configuration from the IDE (for example a database console), or really just have them close to the code (like a linter).
IntelliJ has a task runner built-in that can do all of this very easily, in a way that I can share it with the rest of my team, and don't have to bother with remembering specific commands.
