June 2025 monthly summary: Delivered targeted build and release improvements across three repositories to boost stability, performance, and developer productivity, with a clear focus on business value and reliable versioning. Key features delivered: - playframework/twirl: Built and dependency upgrades to the latest stable toolchain (scala-xml 2.4.0; sbt-scalajs 1.19.0; sbt-ci-release 1.11.1; sbt, scripted-plugin 1.11.2; sbt-bloop 2.0.10; scala3-compiler 3.3.6; scala3-library 3.3.6; parsers 4.13.8; sbt-scalafmt 2.5.5). - playframework/twirl: Code formatting and hygiene improvements using scalafmt 3.9.8 and updated blame-ignore rules with reformatting across the codebase. - sbt/flyway-sbt: CI publishing updated to enable snapshots from the main branch, expanding continuous delivery and feedback. - sbt/sbt-git: Versioning system stabilization achieved by re-enabling sbt-ci-release + dynver, aligning CI workflows to fetch full Git history and fix versioning on CI. Major bugs fixed: - CI versioning inconsistencies addressed in sbt-git, including fixes to CI versioning logic and alignment with the release tooling. - CI/history-related issues mitigated by updating workflows to fetch full repository history for accurate version calculations. Overall impact and accomplishments: - Faster, more reliable builds and releases across three repos; improved compatibility with Scala 3 tooling; more consistent versioning across CI and release pipelines; reduced risk of build regressions due to automated formatting and tool upgrades. Technologies/skills demonstrated: - Advanced Scala tooling upgrades (SBT, Scala 3, scalafmt) and dependency management. - SBt ecosystem proficiency (sbt-ci-release, dynver, sbt-bloop, sbt-scalajs, GitVersioning strategies). - CI/CD optimization (GitHub Actions workflows, full git history fetch, snapshot publishing). - Code quality discipline (scalafmt, blame-ignore handling) and cross-repo collaboration.
