Dependency Management and Plugins

When building Scala projects, you often need functionality that isn't part of the core language. Things like logging, database access, or web frameworks are common examples.

Instead of writing all this code yourself, you can use external libraries (also called dependencies). These are pre-written code packages that other developers have created and shared.

SBT makes it easy to add these external libraries. You declare them in your build.sbt file using the libraryDependencies setting.

Here's the basic syntax:

• "org.group": The organization or group ID.
• % "artifact": The artifact ID (library name). Use %% for Scala libraries to automatically match your Scala version.
• % "version": The specific version of the library you want.

Example:

libraryDependencies += "org.slf4j" % "slf4j-simple" % "1.7.32"
