Maven Connection timed out

[BrightRan]

Associated community ticket: https://github.community/t/maven-connection-timed-out/129040

Recently the customer is receiving a lot of Connection timed out errors in CI builds from maven when pulling dependencies from https://repo.maven.apache.org and similar public repositories. He has never experienced this error locally even when purging local .m2/repository .
The customer is using GitHub-hosted runners in his CI workflow.

Hello, @BrightRan
Would you, please provide the link to workflow, where you've got the connection timed out errors. Also may you clarify the time, when this errors is impacted.
These details help us to investigate this issue.
Thank you.

Hi, I'm facing the same issue for several projects, here an example
https://github.com/kiegroup/appformer/pull/1037/checks?sha=29e3f45162a5e1310d38ec1982adbe0102378662
(I've attached the log in case it's removed and pull_request.yml files appformer_log_and_flow.zip)

We faced the same problem in the past in our internal CI environment (running with jenkins), it seems Maven Central bans and holds the request if there is too many requests, we solved the problem adding a Nexus proxy mirroring maven central. Do you think it's the same? Do you (github) have any kind of internal proxy to deal with it?

Just to provide you more info, same job working well (just java8, java11 is known issue not related with this) self-hosted (my laptop)
https://github.com/kiegroup/appformer/pull/1037/checks?check_run_id=1040516642
So it seems there's some github stuff in the middle 🤔

Hello @Ginxo
How often do you see this problem? Does it appear only for a particular package?
I believe the issue can be addressed directly to Maven Central Community Support, but need to clarify the details above.

We are looking forward to your reply.

HI @Darleev
we have several cases here:

• appformer case. It's very consistent and happens at the same point/same artifact every time the job is run, it can't get org.codehaus.plexus:plexus-interpolation:jar:1.25 artifacts running org.apache.maven.plugins:maven-war-plugin:3.2.2:war
  • you can take any Maven Build (8) from here https://github.com/kiegroup/appformer/pull/1037/checks?check_run_id=1050196122 as an example.
• kie-wb-common case this is not consistent but it fails every time the job is run
  • Failed to collect dependencies at org.seleniumhq.selenium:selenium-java:jar:3.13.0: Failed to read artifact descriptor for org.seleniumhq.selenium:selenium-java:jar:3.13.0: Could not transfer artifact org.seleniumhq.selenium:selenium-java:pom:3.13.0 from/to central
  • Failed to collect dependencies at commons-jxpath:commons-jxpath:jar:1.3: Failed to read artifact descriptor for commons-jxpath:commons-jxpath:jar:1.3: Could not transfer artifact commons-jxpath:commons-jxpath:pom:1.3 from/to central
  • you can take any Maven Build (8) from here https://github.com/kiegroup/kie-wb-common/pull/3401/checks?check_run_id=1050198863
• drools case this is even less consistent than kie-wb-common case. It works most of the times but fails sometimes
  • Failed to collect dependencies at org.asciidoctor:asciidoctorj:jar:2.2.0 -> org.jruby:jruby:jar:9.2.9.0 -> org.jruby:jruby-core:jar:9.2.9.0 -> org.jruby.joni:joni:jar:2.1.30: Failed to read artifact descriptor for org.jruby.joni:joni:jar:2.1.30: Could not transfer artifact org.jruby.joni:joni:pom:2.1.30 from/to central
  • Failed to read artifact descriptor for org.antlr:antlr4-maven-plugin:jar:4.8: Could not transfer artifact org.antlr:antlr4-maven-plugin:pom:4.8 from/to central
  • you can take any Maven Build (8) from here https://github.com/kiegroup/drools/pull/3063

@Darleev Expcept the appformer case, which is very consistent, it's not happening for the same artifact and as I told you I tried with a self-hosted runner and I couldn't reproduce error so it makes me wonder if you have any kind of proxy configuration on your side.
@Darleev thanks for the support, this is blocking our CI

just to provide you more information. I run the build inside a docker container from github action using build-chain@openjdk8 and it's working https://github.com/kiegroup/appformer/pull/1037/checks?check_run_id=1055423092
Every step I do points me there's something "weird" on your (github) side

@Ginxo thank you for the information provided.
We are in the midst of the investigation. I will keep you informed.
