Antlr4 failing to reach out to Maven repository #4703

This morning, I've been having trouble trying to do anything at all with Antlr4. I can't use it to build any of my grammars, and not even antlr4 --help works.

I get the following error output:

Traceback (most recent call last):
  File "/usr/local/bin/antlr4", line 8, in <module>

It appears to be timing out when it reaches out to its Maven repository.

https://search.maven.org/solrsearch/select?q=a:antlr4-master+g:org.antlr. I mentioned this here. https://github.com/antlr/antlr4/issues/4698#issuecomment-2376841225. The change, which should be in the antlr4-tools repo, looks instead to https://repo1.maven.org/maven2/org/antlr/antlr4/, avoiding search.maven.org entirely, which is not robust, frequently down--more often than not!
