Tests: HTTP Error 403: Forbidden #170
Description
Hi. When running the nightly tests, we observed two occasions where requesting a search on Maven Central 1 leads to a HTTP Error 403 response 2, most probably because it (GitHub!) is hammering that API/endpoint a little bit too much at that particular time.
The problem can easily be fixed by re-running the CI job, so it's merely a cosmetic/convenience issue. However, the situation could possibly be improved on a regular maintenance cycle?

While it was about 403's coming from
search.maven.orgbefore, it is aboutcentral.sonatype.com1 now 2.Footnotes

@surister: Is it absolutely required to run a search request to Jar package registries like outlined above, or could this step be omitted and designed differently?
amotl commentedon Feb 26, 2026
@surister: Can the Jar files be fetched through normal mechanisms, like other applications will also not run into rate limiting issues when pulling their Java dependencies into CI environments? Maybe it helps already to set or adjust the HTTP user agent on relevant requests?

I can see this would apparently need to happen on behalf of the
antlr4-toolsPython package, specifically at those spots, right?surister commentedon Feb 26, 2026
One could patch antlr4-tools, yes. Specifically https://github.com/antlr/antlr4-tools/blob/6e6a2a781277d7463369f5248275ee5e7c5eb997/antlr4_tool_runner.py#L47
Didn't do it in the past because typically, a re-run would just pass.

Real issue is tracked at antlr/antlr4-tools#22

It looks like this patch can heal CI already.

Other than the quick fix shared yesterday, this patch and report resembles a better solution, as suggested by @asuol. Thanks!
