   Declaring a `dependencies.toml` file doesn't make it the single source of truth for dependencies: it's a conventional location where dependencies can be declared.
  -As soon as you start using catalogs it's strongly recommended to declare all your dependencies in a catalog and not hardcode group/artifact/version strings in build scripts.
  -But be aware that it's likely that some plugins add dependencies transparently, therefore dependencies defined outside of this file.
  -
  -Just like `src/main/java` is a convention to find the Java sources which doesn't prevent additional source directories to be declared (either in a build script or a plugin), the presence of the `dependencies.toml` file doesn't mean that it's impossible to declare dependencies elsewhere.

   The presence of this file does, however, suggest that most dependencies, if not all, will be declared in this file.
   Therefore, updating a dependency version, for most users, should only consists of changing a line in this file.

negative.code: 
  Dependencies declared in a catalog are exposed to build scripts via an extension corresponding to their name.
  In the example above, because the catalog declared in settings is named `libs`, the extension is available via the name `libs` in all build scripts of the current build.
