sbt

What sbt is

sbt is an open-source build tool for Scala, Java, and other projects. Build definitions use Scala code, allowing build logic to use Scala’s flexibility. sbt manages libraries through Coursier and performs incremental recompilation using information from the compiler. Continuous compilation and testing can run through triggered execution, while tasks can execute in parallel, including tests. Testing support includes ScalaCheck, specs, and ScalaTest; JUnit is available through a plugin. sbt runs on Linux, macOS, and Windows and requires JDK 8 or later. Downloads include universal ZIP and TGZ archives, Windows MSI installers, and SHA-256 and PGP signature files. The project directs community questions to the sbt tag on Stack Overflow and the #sbt channel on Scala Discord. It encourages contributions and credits the Scala Center, an open-source foundation and EPFL unit in Lausanne, Switzerland. The listed sbt plan is free.

Who it suits

sbt suits developers building Scala or Java projects who need code-based build definitions, dependency management, incremental compilation, testing, and parallel tasks. It supports Linux, macOS, and Windows systems with JDK 8 or later.

Limits

sbt requires JDK 8 or later. JUnit testing is available through a plugin rather than the core testing integrations.

Getting started

1. Install JDK 8 or later
2. Open the sbt website
3. Download a universal ZIP or TGZ package, or a Windows MSI installer
4. Verify the available SHA-256 or PGP signature files
5. Create build definitions using Scala code
6. Use Coursier for project library management

Verdict

sbt provides Scala-based build configuration, dependency management, incremental compilation, testing, and parallel execution across major desktop operating systems. Its JDK requirement and plugin-based JUnit support are the main setup points to note.
