As this ticket was closed, but the error is now present from RC2 on, what is the solution ?

[magnus-larsson]

Hopefully, there will soon be another RC released of springdoc-openapi 3.0.0.

Meanwhile you can use the snapshot builds. For Gradle that is:

repositories {
    ...
    maven { url = 'https://central.sonatype.com/repository/maven-snapshots/'}
}

dependencies {
    ...
    implementation 'org.springdoc:springdoc-openapi-starter-webflux-ui:3.0.0-SNAPSHOT'

[goafabric]

thank you

@magnus-larsson and @goafabric,

We depend on the release of Spring Boot 4.0.0-RC3, which is expected to incorporate some important API versioning updates from Spring Framework 7.0.0-RC4.

In the meantime, for your own testing purposes, you can continue using 3.0.0-RC2-SNAPSHOT, which relies on:
Spring-boot 4.0.0-SNAPSHOT.

PS: I understand the need for an intermediate release, but due to multiple ongoing commitments, it's currently not possible for me to dedicate additional time for another RC release, before spring-boot RC4.

@bnasslahsen
thx 4 the reply ... i see no urgent need for an intermediate release Boot 4.0 GA should anways hit next week.
I honestly find it more baffling, that spring keeps introducing breaking changes in the RC phase.
But now that we are talking, i am having a more general question for a longer time:

Would it be possible to have springdoc more close corelated to spring boot itself ?
I Mean as of this day, spring has no OpenAPI framework itself and springdoc is somehow the defacto standard.
Yet there is always the problem if there is a breaking change in Spring, it will hit SpringDoc during runtime.

With e.g. Quarkus its different, Quarkus and the OpenAPI Dependency itself are provided by the same people.
But .. just asking if that is a possible consideration

[bnasslahsen]

@goafabric,

Unless there's a last-minute issue, I can confidently say we'll release on the same day as Spring Boot 4.0!
Thanks a lot for your response—much appreciated.

[mp911de]

I honestly find it more baffling, that spring keeps introducing breaking changes in the RC phase.

Major releases happen only once in a couple of years. Delaying such changes to the next major release would have positioned in a worse position preventing introduction of certain new functionality. Moving such a fundamental change to the next major release (4-5 years) would delay new features improving developer productivity and refactoring-safety by another 5 years.

Our budget for breaking changes in minor feature releases is almost non-existent. You have already recognized that breaking changes even in major releases have quite some impact, not only on applications but everyone that integrates with Spring Data. By carefully balancing our options against various tradeoffs, this choice is the one with the least negative long-term consequences yet creating discomfort for about two weeks for more-than-early adopters.

In any case, thanks for your speedy adoption.

[goafabric]

@mp911de Thank you very much for the clarification, i did not expect this.
I guess this is not the right place here, but unfortunately there are a lot of breaking changes in spring boot 4.0 already, which i tried to mitigate with openrewrite .. and others will to.
So this i was puzzled to find more in the RC2 .. but anyways i get your point ...
As a spring user for about 15 years, a big thanks to you guys for pushing forward
