What's inside Contraband

  1. Overview of sbt build tool

    sbt is a build tool for Scala and Java projects. It provides the following core capabilities: downloading library dependencies via Coursier, incremental compilation and testing, integration with IDEs such as IntelliJ and VS Code, and packaging JAR files for publication to the Central repository (the JVM community package registry).

  2. Overview of sbt build tool

    sbt is a build tool for Scala and Java that handles library dependency downloads via Coursier, incremental compilation, testing, IDE integration (IntelliJ and VS Code), JAR packaging, and publishing to the Central Repo.

  3. Overview of Contraband

    Contraband is a description language for datatypes and APIs that targets Java and Scala. It allows developers to describe API types and fields to automatically generate Java classes or pseudo case classes in Scala, as well as JSON bindings for those datatypes. It is designed to support API evolution over time.

  4. Overview of sbt build tool capabilities

    sbt is a build tool primarily used for Scala and Java projects. Its core functionality includes:

    • Downloading library dependencies using Coursier.
    • Performing incremental compilation and incremental testing.
    • Integrating with IDEs such as IntelliJ and VS Code.
    • Creating JAR packages.
    • Publishing artifacts to the Central Repository used by the JVM community.

  5. Overview of sbt build tool capabilities

    sbt is a build tool for Scala and Java projects. Its primary capabilities include:

    • Dependency management: Downloads libraries using Coursier.
    • Build lifecycle: Performs incremental compilation and testing of projects.
    • IDE Integration: Integrates with editors such as IntelliJ and VS Code.
    • Distribution: Packages projects into JAR files and publishes them to the Central repository (the JVM community package registry).

  6. Overview of sbt architectural components

    sbt consists of several key components:

    • sbt runner: The sbt shell script that initiates the build process.
    • sbt server: The main build tool instance (versioned via project/build.properties) that handles requests from clients or IDEs.
    • sbtn (sbt --client): A native thin client compiled with GraalVM used to send commands to the sbt server.
    • Coursier: A dependency resolver used by sbt server for Scala libraries and compilers.
    • Zinc: An incremental compiler for Scala that provides a stable API across multiple Scala versions.
    • BSP server: Support for the Build Server Protocol, allowing IDEs like IntelliJ and Metals to communicate with a running sbt server.

  8. Overview of sbt (Scala Build Tool)

    sbt is a build tool for Scala and Java that allows developers to declare sub-projects, dependencies, and custom tasks to ensure fast and reproducible builds. It automates the downloading of the Scala compiler and manages dependencies via Coursier. It uses Zinc for incremental compilation of Scala and Java source code and follows Maven repository conventions for publishing packages.

  9. Overview of sbt core features and capabilities

    sbt is a build tool designed for Scala and Java projects with the following key capabilities:

    • Cross-building: Ability to build projects against multiple Scala versions.
    • Typesafe DSL: build.sbt uses a Scala-based DSL, meaning configuration typos are caught as compilation errors.
    • Incremental Compilation: Uses the Zinc incremental compiler and a file watch mode (~) to accelerate the edit-compile-test loop.
    • Extensibility: Supports plugins for adding new tasks or platform support (e.g., Scala.js).

  10. Overview of sbt build tool

    sbt is a build tool primarily for Scala and Java. It handles library dependency downloads via Coursier, incremental compilation and testing, integration with IDEs such as IntelliJ and VS Code, creation of JAR packages, and publishing to the Central Repo used by the JVM community.

  11. Overview of sbt build tool for Scala and Java

    sbt is a build tool designed for Scala and Java that provides fast, reproducible builds by automating the management of sub-projects, dependencies, and custom tasks. It eliminates the need to manually invoke the Scala compiler (scalac) and manually manage JAR files. Key features include:

    • Automatic compiler downloading based on the specified Scala version.
    • Dependency resolution via Coursier.
    • Incremental compilation of Scala and Java source code using Zinc.
    • Parallel task execution.
    • Standardized conventions for publishing packages to Maven repositories for JVM ecosystem interoperability.

  12. Overview of Cross-Building in sbt

    Cross-building is the process of building the same set of source files for multiple targets. This includes:

    • Scala Cross-builds: Targeting multiple Scala releases.
    • Platform Cross-builds: Targeting different platforms like JVM, Scala.JS, and Scala Native.
    • Virtual Axes: Targeting different versions of external frameworks, such as Spark versions.
