Captured 2026-09-18 from repo1.maven.org (Maven Central): https://repo1.maven.org/maven2/org/springframework/boot/spring-boot-starter-aspectj/4.1.1/spring-boot-starter-aspectj-4.1.1.pom org.springframework.boot spring-boot-starter-aspectj 4.1.1 spring-boot-starter-aspectj Starter for using aspect-oriented programming with AspectJ org.springframework.boot spring-boot-starter 4.1.1 compile org.springframework spring-aop 7.0.9 compile org.aspectj aspectjweaver 1.9.25.1 compile The renamed starter's own POM declares exactly spring-aop + aspectjweaver as compile dependencies -- the same two jars this module's own pom.xml already lists as the reason it depends on spring-boot-starter-aspectj. There is no missing third piece and no behavioural difference from assembling the two jars by hand; the starter just does it for you, correctly versioned, in one line.
