Я недавно начал работать в новом месте, где они используют scala и играют для этого старого приложения. К сожалению, здесь никто не знаком с этой ошибкой, и я надеюсь, что какой-нибудь гораздо более опытный scala человек сможет пролить немного света здесь.
На Ма c ОС (Каталина) Я получаю эти ошибки, но когда я помещаю все в linux ВМ, я могу заставить его работать! Так, это специфицирует c для OS X.
