Compilation failure: spring-boot-amqp-messaging/src/main/java/com/thepracticaldeveloper/rabbitmqconfig/CustomMessage.java:[7,8] class, interface, or enum expected

[mh-github]

I am using Java 18.

First error I got was:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project spring-boot-amqp-messaging: Fatal error compiling: error: invalid target release: 17 -> [Help 1]
$ mvn spring-boot:run
So, I commented java.version in pom.xml

<properties>
	<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
	<!-- <java.version>17</java.version> -->
</properties>

Then I got the following error:

[ERROR] /mnt/d/Code/Java/spring-boot-amqp-messaging/src/main/java/com/thepracticaldeveloper/rabbitmqconfig/CustomMessage.java:[7,8] class, interface, or enum expected
[ERROR] /mnt/d/Code/Java/spring-boot-amqp-messaging/src/main/java/com/thepracticaldeveloper/rabbitmqconfig/CustomMessage.java:[7,51] class, interface, or enum expected
[ERROR] /mnt/d/Code/Java/spring-boot-amqp-messaging/src/main/java/com/thepracticaldeveloper/rabbitmqconfig/CustomMessage.java:[8,52] class, interface, or enum expected
[ERROR] /mnt/d/Code/Java/spring-boot-amqp-messaging/src/main/java/com/thepracticaldeveloper/rabbitmqconfig/CustomMessage.java:[9,50] class, interface, or enum expected

How do I fix this error? Looks like I need an import in CustomMessage.java for 'record'.
