I was able to make it works by setting rxjava to 2.2.0 version.
I am not sur that the best solution but it works on my machine ;-)

        <dependency>
            <groupId>io.reactivex.rxjava2</groupId>
            <artifactId>rxjava</artifactId>
            <version>2.2.0</version>
        </dependency>

Yes, that issue is an unfortunate side-effect of vertx importing an older incompatible version of rxjava. What does your pom.xml look like? Did you import vertx manually at all?

[kanedafromparis]

Actually, on my first try, I had a transitive dependency to vertx 3.5.3, but when I remove this dependency ( my project was at hello world stage, so i could tray) I still had this issue. Anyhow, I would probably import vertx manually (I prefer its json library.) but does my workaround is correct ? Le lun. 6 août 2018 à 14:00, Stéphane Épardaud <notifications@github.com> a écrit :

Yes, absolutely. In fact Redpipe imports that newer version of rxjava. But Maven picks up the older one via the import of vertx.

[kanedafromparis]

Great, thanks you. And thank you for this project seems very, very promising. Le lun. 6 août 2018 à 15:18, Stéphane Épardaud <notifications@github.com> a écrit :
