Release Notes

square/gradle-dependencies-sorter (com.squareup.sort-dependencies)

v0.21.0

• [Feat]: sort dependency constraints blocks by default.
• [Feat]: add --block and blocks(...) for sorting custom Gradle DSL blocks in Kotlin and Groovy build scripts.
• [Fix]: preserve indentation in nested dependencies blocks.
• [Fix]: fix partial matches in the dependency types being sorted backwards.
• [Fix]: add missing dependency types androidTestCompileOnly and androidTestRuntimeOnly.
• [Fix]: sort nested project paths after hyphenated siblings.
• [Chore]: Update kotlin-editor to 0.26, which includes fixes for things like multi-dollar strings and lower Kotlin language version targeting to avoid kotlin-metadata-jvm conflicts and better Gradle 8.x compat.

v0.20.0

• [Feat]: bump kotlin-editor.
• [Feat]: bump gradle-script-grammar.
• [Fix]: don't register tasks for projects without a build script. Applying the plugin to an intermediate "container"
  project (e.g. :sub in include(":sub:project")) wired a non-existent build file as a required task input, which
  Gradle's strict input validation fails as a hard error under Gradle 9.
• [Fix]: sort type-safe project dependencies before external libraries.

v0.19.0

• [Feat]: support parsing and sorting dependencies blocks with dot syntax.
