Autoconfiguration not working in Spring boot 3.0.0-RC2

Hello,

When I follow your instructions for Maven and Spring Boot to configure the environment, I get a lot of exceptions when the server starts.

I have had to manually copy GraphQlDateTimeAutoConfiguration, GraphQlDateTimeProperties and GraphQlDateTimeScalarsAutoConfiguration to my project, and then it works. For any reason, your autoconfiguration seems to not be working with Spring boot 3.0.0-RC2. I am also using Java 19 (just in case it could be also related to the issue).

Find some exceptions examples here:

I will release a new major version this week which will support the Spring Boot 3.0.

Thank you! It works perfectly well now. Just to add a little detail to your answer: the full filename I have used has the extension “imports”. ${YOUR_PROJECT}/src/main/resources/META-INF/spring/org.springframework.boot.autoconfigure.AutoConfiguration.imports
