Mr @SGaist please any idea? this problem persist one week, i am still blocked with my app

SGaist

I'd start with a default project and ensure that it builds and run properly, then add the Java parts from scratch using new files.

SGaist

Looks wrong:
@ENSAO_CHEIKH said in use Java code in Qt prolem of compilation:

-Dfile.encoding

there should be a value there.

ENSAO_CHEIKH

@SGaist pkease in which file I find this -Dfile.encoding, I dont see it ?

ENSAO_CHEIKH

@SGaist please where can I put this -Dfile encoding?

SGaist

Please show some patience and allow at least 24 hours to pass before bumping your own thread. This is a voluntary driven forum and people may not live in the same time zone as you.

I currently do not have a Windows machine at hand to check your issue.

That said:

did you try to apply my suggestion to start from a default project and once it's built, add the Java part ?
did you check your gradle related files for encoding entries ?
