                  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.

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

                        -Dfile.encoding

                        there should be a value there.

                          -Dfile.encoding

                          there should be a value there.

                              • 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 ?
