Use for JVM build, packaging, and testing — Gradle 8.10+ with Kotlin DSL, libs.versions.toml version catalogs, java/kotlin toolchains, convention plugins (buildSrc / build-logic), configuration cache + parallel builds; publishing libraries to Maven Central via maven-publish + nmcp + JReleaser, signing with useInMemoryPgpKeys, JPMS module-info, GitHub Actions release-on-tag; testing with JUnit 5 (Jupiter), AssertJ, kotest (Kotlin), mockk / mockito, Testcontainers, JaCoCo, awaitility. Read the matching reference before acting.
