Migrate a Maven or Gradle project one Java LTS step from Java 11 to Java 17: it must compile under JDK 17, conserve every previously-passing test, and raise the effective compiler target to 17, using only standard tools (JDKs, Maven or Gradle, OpenRewrite recipes from Maven Central; no project-specific scripts). Use for an 11→17 Java LTS bump.

From the source SKILL.md

Migrate the project in your working directory from Java 11 to Java 17. Goal: it compiles and passes its tests under JDK 17, conserving every test that passed under JDK 11, with the effective compiler target raised to 17 (a project that merely compiles under 17 but still targets 11 is not a bump). Work autonomously until done.
