Release Notes

diffplug/spotless (com.diffplug.spotless:spotless-maven-plugin)

v2.39.0

Added

• Jvm.Support now accepts -SNAPSHOT versions, treated as the non-SNAPSHOT. (#​1583)
• Support Rome as a formatter for JavaScript and TypeScript code. Adds a new rome step to javascript and typescript formatter configurations. (#​1663)
• Add semantics-aware Java import ordering (i.e. sort by package, then class, then member). (#​522)

Fixed

• Fixed a regression which changed the import sorting order in googleJavaFormat introduced in 2.38.0. (#​1680)
• Equo-based formatters now work on platforms unsupported by Eclipse such as PowerPC (fixes durian-swt#20)
• When P2 download fails, indicate the responsible formatter. (#​1698)

Changes

• Equo-based formatters now download metadata to ~/.m2/repository/dev/equo/p2-data rather than ~/.equo, and for CI machines without a home directory the p2 data goes to $GRADLE_USER_HOME/caches/p2-data. (#​1714)
• Bump default googleJavaFormat version to latest 1.16.0 -> 1.17.0. (#​1710)
• Bump default ktfmt version to latest 0.43 -> 0.44. (#​1691)
• Bump default ktlint version to latest 0.48.2 -> 0.49.1. (#​1696)
  • Dropped support for ktlint 0.46.x following our policy of supporting two breaking changes at a time.
• Bump default sortpom version to latest 3.0.0 -> 3.2.1. (#​1675)
