Subject RE: Converter Plugin not loaded
Date Sun, 20 Jul 2014 07:54:30 GMT
The manual still references the maven exec plugin. That should be removed, no?

My problem was that I didn't enable annotation processing in Intellij.

Works fine now, thanks.

Best Regards,

I updated the manual in regards to how to use the annotation processor if it doesn't work
by default. It helps to compile your code using Maven, Gradle, Ant, or some other standard
build tool rather than through the IDE.
