Oi Silvia

Você está utilizando algum proxy?

O da empresa tá barrando baixar e executar a aplicação

Oi Silvia tudo bem?

Nesse caso você precisa falar com o gestor da rede da sua empresa para ele poder liberar o acesso da sua aplicação.

Ok. André, Bom dia!

Consegui resolver este problema, através das dicas do site abaixo:

https://gist.github.com/armoucar/1309272

Com essa configuração, consegui passar as informações do proxy da empresa e efetuar o login nele. E com isso, consegui baixar as dependências, porém, está ocorrendo o erro abaixo ao executar no prompt de comando o comando: ant jetty.run.
