## What it is
sbt is the interactive build tool for Scala and Java projects, using a Scala-based DSL (build.sbt) to define parallel task graphs. It provides incremental compilation via Zinc, dependency management through Coursier, testing, packaging, and publishing to Maven Central.

## Use cases
- build a scala project
- cross-build against multiple scala versions
- incrementally compile and test scala code
- publish jars to maven central
- scaffold a new scala project from a template
- manage java and scala library dependencies

## When to choose
- you are building a Scala or Java project, especially multi-module or cross-built against several Scala versions
- you want fast edit-compile-test loops with incremental compilation and file watching
- you need an extensible build with a large plugin ecosystem (Scala.js, Play, etc.)

## When to avoid
- you are building a simple non-JVM project better served by a lighter tool
- your team dislikes Scala-based build DSLs and prefers declarative formats like YAML or TOML
- you need extremely fast cold builds on huge projects where alternative tools may be simpler
