This is a low level network error while trying to connect to maven central. My guess is that you have some sort of network barrier preventing a direct connection. If you need to use a proxy for making external connections, see section 20.2 of the user guide for instructions on configuring a proxy.

Hi Gary,

Thank you very much. That worked.

But now got into a different issue:

//////////////////////////////////////

/////////////////////////////////////////////////// end of message

My source code in .jjt file and I need to preprocess it with jjtree before sending it to javacc. private AstUELExpression uel_value_expression() #UELExpression : {} {

value_expression() { return jjtThis; } }

I wonder whether there is link how to use the correct plugin for a successful compilation.
