Hello Alessio,
If the problem is in Karaf, you probably aren't doing a clean boot, so you
should be using the unmodified version as noted in the previous post.
1. Make sure you compiled the PLC4X project with the modification in clean
form ("> mvn clean install -DskipTests").
2. Perform a clean boot of Karaf, or preferably delete the "data" and
"system" directories of your installation and run "> karaf clean"
3. Install the feature and your application.
4. If it fails you should verify that your Maven installation uses
SNAPSHOTs only from your local repository.
At this point It should work,
I'll be waiting for your confirmation,
Best regards,
