Support Spring Boot 4

[alexkops]

Problem Statement

I'm currently testing my application with Spring Boot 4.0.0-M2 and with the current sentry gradle plugin 5.9.0 in my build file, I will get the following error on start:
Could not find class [org.springframework.boot.autoconfigure.web.reactive.function.client.WebClientAutoConfiguration]
That's because of the modularisation efforts, the WebClient has it's own module now and the class moved to
module/spring-boot-webclient/src/main/java/org/springframework/boot/webclient/autoconfigure/WebClientAutoConfiguration.java

It would be great if the Sentry Spring Boot 4 support would be ready by the time the final version is released.

JAVA-148 Support Spring Boot 4

Hello @alexkops thanks for reporting in. We've just recently added modules for Spring Boot 4 / Spring 7 but haven't released them yet. Those are currently targeting the M1 release.

We will soon take a look at targeting the M2 release.

What you're describing should already be taken care of by what we have. We're tracking support in #4080

Not quite sure yet when we'll do another release, but we can try to get one out soon, just wanted to take a quick look at M2 first. Where I haven't manually tested changes in #4665

@alexkops, we've just released https://github.com/getsentry/sentry-java/releases/tag/8.21.0 which adds sentry-spring-boot-4 and sentry-spring-7, supporting M2.

Can you please test if this solves the problem?

[alexkops]

Hmm, maybe you can give me a hint on how to properly test it. The only Sentry dependency I have in my gradle build file is usually id("io.sentry.jvm.gradle") version "5.9.0"
But that doesn't reliably load the latest version as I found.
So I added

implementation(platform("io.sentry:sentry-bom:8.21.0") )
implementation("io.sentry:sentry-spring-boot-4-starter")

But the error still appears, probably because I also have still io-sentry-spring-boot-jakarta:8.21.0 in my classpath, as I see in IntelliJ. I guess that is brought in by the gradle plugin.
After commenting out the gradle plugin and the configuration I use it for, it works.
Is there any way to make the gradle plugin use the correct version?

Hey @alexkops, yep I just checked and it seems the Gradle plugin still tries to bring in io-sentry-spring-boot-jakarta causing the failure. We'll look into this and provide a fix.
