# Building error "usb-modeswitch" in AOSP

hey !
I have an error when I build the aosp.
I made some changes, and I get this error
error: external/usb_modeswitch/jni: MODULE.TARGET.EXECUTABLES.usb_modeswitch already defined by /external/usb-modeswitch.
what shall I do ? Thanks

@taimed About AOSP, maybe @jasonl can help you

what changes you made ? you can try to restore your changes

@jasonl I can restore changes, I have added the usb modeswitch from a third party

already resolved ! deleted the duplicate definition
