scala/community-build

This system is the Scala 2 Community Build, a tooling infrastructure designed to compile and test a wide ecosystem of external Scala libraries against a specific version of the Scala compiler. It manages dependencies by pinning specific Git commits for numerous projects and tools, ensuring reproducible builds across various JDK versions. The system includes operational scripts for local execution, SHA advancement, and reporting, along with Jenkins integration for automated nightly builds.

The repository is initialized with the core infrastructure for the Scala 2 Community Build. This includes the Apache 2.0 license, a Code of Conduct, and a .gitignore file. The build system is configured via community.conf and projs.conf, utilizing dbuild version 0.9.20 and sbt 1.13.0. A nightly.properties file sets the default Scala version to 2.13.19-bin-8b318bf. Operational scripts (run, advance, narrow, report) are added to manage local builds, advance project SHAs, and generate reports. The README is updated to describe the project's purpose and maintenance by VirtusLab.

(repo-wide) · high confidence

A new Jenkins job script has been added to manage the community build. It configures Java options for JDK 11+ compatibility, adds Coursier to the PATH, and allows limiting the build to specific projects via the \$projects\ parameter.

scripts/jobs · high confidence

An empty log4j.properties file has been added to the scripts directory. This file currently contains no configuration settings, meaning it will not affect logging behavior until properties are defined within it.

scripts · low confidence

This change updates the configuration files in the \proj/\ directory for numerous Scala libraries (including advxml, airframe, akka-http-json, ammonite, breeze, circe, and others) to point to specific commit SHAs. These updates reflect ongoing maintenance to keep the community build compatible with upstream projects, often involving unfreezing previously frozen repos, adjusting build commands to handle test exclusions or GPG requirements, and ensuring extraction works on various JDK versions.

proj · high confidence

The build system now includes explicit configuration files (\.conf\) in the \core/\ directory for key Scala libraries and tools: acyclic, genjavadoc, kind-projector, scalafix, scalafmt, scalameta, silencer, and wartremover. These files define the specific Git URIs, commit SHAs, and build options (such as excluded projects or test filters) required to fetch and compile these dependencies within the community build environment, ensuring stable and reproducible builds for these external tools.

scala/community-build was measured the same way every project in this corpus was: the same rubric, at a pinned commit, with the result published in full. Point a surveyor at a repository you know and see whether you agree with it.
