RestartLauncher cannot access class

[dadzio008]

Hi everyone!
I'm creating spring boot app, but i have a problem to run app with all dependencies.

pi@raspberrypi:~/Desktop/distribution $ sudo ./run.sh
Exception in thread "restartedMain" java.lang.IllegalAccessException: class org.springframework.boot.devtools.restart.RestartLauncher (in module spring.boot.devtools) cannot access class com.example.myprojectraspi.MyProjectRaspiApplication (in module com.example.myprojectraspi) because module com.example.myprojectraspi does not export com.example.myprojectraspi to module spring.boot.devtools

I don't know whats wrong. Anyone could help?

From the error message:

org.springframework.boot.devtools.restart.RestartLauncher (in module spring.boot.devtools) cannot access class com.example.myprojectraspi.MyProjectRaspiApplication (in module com.example.myprojectraspi) because module com.example.myprojectraspi does not export com.example.myprojectraspi to module spring.boot.devtools

it sounds like there is an export clause missing in your module.java file.

You probably need to add a line like this:

exports com.example.myprojectraspi;

and maybe other exports if spring needs to access other classes inside your app.

Not a Pi4J issue, but I hope this helps :-).
(unless Pi4J is crashing something on startup, but would need more logging info to determine that.)

Thanks, Robert
