Hi Did you initialize the extension

Oleg Nenashev · Answer

So basically you need to run `mvn clean compile` so that the extensions are downloaded <https github com wiremock wiremock testcontainers java blob main pom xml L140 L170>

FTR <https github com wiremock wiremock testcontainers java tree main using wiremock extensions>
