Hi,
I've update my app, removing old Pi4J library and using Pi4j2
Library and it's dependencies are in 'Additional Libraries' folder.
When I'm compiling app, I get this error:
"

class file has wrong version 55.0, should be 52.0
Please remove or make sure it appears in the correct subdirectory of the classpath.

How to compile my project?
Thanks.
