I believe I don't even have jacoco installed I don't know why is this message appearing

Please do not split topics across several threads. This makes following the conversation in the threads view very hard as the context of the other messages is missing. If you have additional information either edit the original message or post to its thread. Regarding the problem, how is this Gradle-related more than that you use Gradle to run your build? And also, what is your problem actually? Looks like just a warning that the version is downgraded automatically. As you use Flutter, your dependencies are included as subprojects, so even if you do not use JaCoCo, maybe one of your dependencies does? And if so, maybe it is not compatible to the versions you use?

probably best to run the cli task that printed this error with --scan to find out where it's coming from. You could link that here
