flyway connection error for r2dbc in testcontainers in Spring boot versions >= 3.x.x about spring-boot HOT 3 OPEN

Can you please share a minimal example that reproduces the behaviour that you have described? Unless the failure is specific to Kotlin, that example should be written in Java in order to minimise the number of moving parts.

sure. I will share a minimal example written in Java.

Just reiterating to emphasize that the testcontainers r2dbc test code written in kotlin works well for Spring Boot 2.7.18 but throws flyway connection error for any version of Spring Boot 3.x.x

from spring-boot.

This public git repo contains the minimal java code showing the problem with flyway, r2dbc, testcontainers and Spring Boot versions >= 3.0.0.

https://github.com/sakthi-logn/spring-boot-flyway-r2dbc-testcontainer.git

Please do the following steps to reproduce the problem:

1. install docker on your machine because testcontainers needs to connect to the docker daemon.
2. clone the repo
3. change directory to the root of the repo and run ./gradlew clean build test --info to see that there are no errors with Spring boot 2.7.18
4. In the build.gradle.kts file, uncomment the line number 3 which containsid("org.springframework.boot") version "3.2.4"
   and comment line number 4 which contains id("org.springframework.boot") version "2.7.18"
5. rerun step 3 to see the same flyway connection error shown in my earlier comments. The only change done was the upgrade to spring boot 3.2.4

I also tried overriding flyway version to the latest using maven BOM overrides in the kotlin gradle.build.kts file but the same error occurred again. So i am not sure if the problem is with flyway.

Please let me know if you need more information.
