Project generator failure in Ac6 SW.
Java represents paths according to current system, so the separators ('\' and '/') shouldn't be hardcoded in string comparison. However, java also provides the possiblitiby to obtain suitable separator to make the code platform independent during file operations, but it is a little more complicated than using static strings.
I really hope that such problems will be fixed because Linux is my development platform since a very long time and SW4STM32 is the first free Linux IDE that uses open source toolchains and provides project configurations for all STM32 microcontrollers, boards and external libraries "out of the box".
