Oi Maciel, tudo bem ?

Cara, será que está tudo configurado corretamente ?

Além disso, não há nenhum proxy na rede ?

Ola Matheus,

como não tem nada mostrando como configura no curso,

segui um tutorial no endereço abaixo que achei na net.

https://documentacao.senior.com.br/fad/5.8.9/informacoes-tecnicas/java/instalacao-apache-ant.htm

Dá uma olhada nesse e ve se foge muito do que fez https://www.mkyong.com/ant/how-to-install-apache-ant-on-windows/

Matheus ainda não achei o erro,

quando rodo aparece o log abaixo:

Vou dar uma olhada e ver o que rolou

Boa noite,

Encontrou alguma solução ?

Consegui fazer rodar na minha máquina, estava investigando o motivo de não ter rodado na sua, quer me falar um pouco do seu ambiente ?

windows 10 64 bits

Era configuração mesmo, ja resolvi.
