O JDK-9 não me permite usar Strings: "java.lang.String é ambíguo"?
Há uma semana, todos os projetos que eu trabalhava estavam funcionando normalmente, mas quando atualizei meu Eclipse para a versão Oxygen e instalei o JDK-9, as coisas ficaram estranhas. Quando tento usar Strings, depois de algum tempo (mais como toda vez que eu salvo o projeto), o compilador gera um erro para cada String no meu projeto.
Tipo de string sendo reconhecido como uma classe ambígua
"O tipo java.lang.String é ambíguo"
Então, eu tentei importarjava.lang.String para ver se corrigiu o erro:
Não :(
Tentei pesquisar essas mensagens no Google e no SO, mas não encontrei nada ...
No entanto, o código em execução no JDK 8 parece funcionar normalmente, confira:
Erro: método principal não encontrado na classeme.mateusakino.ypul.yPuLTester, defina o método principal como:public static void main(String[] args) ou uma classe de aplicativo JavaFX deve estenderjavafx.application.Application
