Unable to configure S3 running with Spring Boot 4

[espada-edalex]

Type: Bug

Component:
S3

Describe the bug

I have been testing the Spring Boot 4.0.0-RC1 upgrade and come across an issue with the S3 autoconfigure. The whenNonNull method has been removed in Spring Boot 4 and will now only call the method if the return isn't null (see: spring-projects/spring-boot@239f384).

I release this is an unreleased version of Spring Boot, but I couldn't see any other issues around v4 compatibility.

Sample

    An attempt was made to call a method that does not exist. The attempt was made from the following location:
    
        io.awspring.cloud.autoconfigure.s3.properties.S3Properties.toS3Configuration(S3Properties.java:205)
    
    The following method did not exist:
    
        'org.springframework.boot.context.properties.PropertyMapper$Source org.springframework.boot.context.properties.PropertyMapper$Source.whenNonNull()'
    
    The calling method's class, io.awspring.cloud.autoconfigure.s3.properties.S3Properties, was loaded from the following location:
    
        jar:file:/home/ubuntu/.m2/repository/io/awspring/cloud/spring-cloud-aws-autoconfigure/3.4.0/spring-cloud-aws-autoconfigure-3.4.0.jar!/io/awspring/cloud/autoconfigure/s3/properties/S3Properties.class
    
    The called method's class, org.springframework.boot.context.properties.PropertyMapper$Source, is available from the following locations:
    
        jar:file:/home/ubuntu/.m2/repository/org/springframework/boot/spring-boot/4.0.0-RC1/spring-boot-4.0.0-RC1.jar!/org/springframework/boot/context/properties/PropertyMapper$Source.class
    
    The called method's class hierarchy was loaded from the following locations:
    
        org.springframework.boot.context.properties.PropertyMapper.Source: file:/home/ubuntu/.m2/repository/org/springframework/boot/spring-boot/4.0.0-RC1/spring-boot-4.0.0-RC1.jar

Hey @espada-edalex ,

This is expected since Spring Cloud AWS 4.0.0-M1 and 4.0.0-RC1 are not released.

Spring Cloud AWS 4.0.0 will be compatible with Spring Boot 4.0.0 dependency.
Once we do the release you will be able to lift version of Spring Cloud AWS and it will work.

Thanks @MatejNedic, I thought as such. Is there anywhere publicly available to see the progress of Spring Cloud AWS 4.0.0? Or an alpha/beta/rc that I can pull in to test now? 🙇

Hey hey,
Yes there is!

You can follow the PR for M4 upgrade. This will be good indicator that we are close to 4.0.0-M1. once it is merged

There is also Milestone 4.0.0.

Since it is not a bug I will be closing this issue.
