Depois de tantas tentativas finalmente resolvi meu problema e para ajudar os outros estou postando aqui a solução.
Estrutura do projeto deve ser assim
e pom.xml deve ser assim

Agora vou te explicar meu erro. observe atentamente a parte de construção de Question. no plugin ant-run quando vamos na tarefa fx:deploy aqui você descobre que eu tenho a entrada do caminho de classe. eu estraguei essa parte que era tão simples. olhe agora no meu Pom aqui. caminho de classe agora atualizado. primeiro eu menciono o diretório base, em seguida, o caminho do plug-in ant-fx e, em seguida, o caminho do jfxrt.jar. jfxrt pode não ser necessário. depois disso, removi a seção de dependências do plugin. isso é crítico. se eu não remover esta seção, meu plugin antrun sempre procura nas dependências fornecidas pelo maven, mas não no ant-classpath. na ordem ant-classpath é muito importante. seu basedir deve sempre vir antes de ant-run.jar . é isso
Espero que isso seja útil para as pessoas que enfrentarão esse problema.
