wildfly-swarm launch from Eclipse “org.jboss.modules.ModuleLoadException”

Question

For multiple projects, I use wildfly-swarm to avoid installing a webserver. The swarm jar file is generated and I can successfully launch it through "java -jar mypackage-swarm.jar".

However, to debug it easily, I would like to launch it via my IDE (eclipse). Either by directly launching my main class or using fakerplace, I have the following exception :

Fakereplace is running.

I've found similar exceptions on internet, but I cannot find a solution.

Has anyone any idea on this ?

Answer 1

Why don't you just run it as jar application ? I'm not sure how to do that in eclipse below is example in intellj but for eclipse you can find your solution here:
