Clean build triggers a compilation warning

[snicoll]

In what version(s) of Spring for Apache Kafka are you seeing this issue?

main

Describe the bug

That's not really a bug but the project does not build cleanly:

To Reproduce

Invoking ./gradlew :spring-kafka:compileJava --rerun-tasks leads to:

> Task :spring-kafka:compileJava
/Users/snicoll/workspace/work/spring-kafka/spring-kafka/src/main/java/org/springframework/kafka/listener/adapter/MessagingMessageListenerAdapter.java:553: warning: [try] auto-closeable resource scope is never referenced in body of corresponding try statement
                        try (var scope = observation.openScope()) {
                                 ^
1 warning

This was added in June so I wonder what's going on.

Courtesy of @wilkinsona explaining my mistake. This isn't actually a build failure (as I think it was when I reported the issue) but "just" a compiler warning. What I mean when I wrote "does not build cleanly" was a build failure but that isn't happening and it looks like I overlooked the log message. Sorry about that and thanks for the quick fix!
