Git pull appears unable to unlink old a mistake you shouldn't have made

In daily development, when someone in the team commits the new code into a jar file and does not rename it, the error "error:unable to unlink old ' Test/lib/xxx-1.0.0.jar ' (Invalid Argument) ". I look very puzzled, said that the old link can not be canceled, but also that the jar package internal changes caused the conflict, in fact, this is only the jar package is being used to cause, the solution is to stop the running code after the Git pull again.
