first build fails on ubuntu due to repo1.maven.org/maven2 timing out for orr.clojure artifact

Question

clj command fails to build classpath on new installation!!!

Running a new installation of POP os, which is a late ubuntu derivative. I've run into this issue on my m1 mac as well. However, after removing the .m2 homedir the problem was solved. But on linux the issue persists.

using adopt temurin 17 jdk + jre

clj version: 1.11.1

all install steps followed from the docs were successful without issues. until you run clj or clojure from cli. The following trace is produced:

Error building classpath. Failed to read artifact descriptor for org.clojure:clojure:jar:1.11.1
org.eclipse.aether.resolution.ArtifactDescriptorException: Failed to read artifact descriptor for org.clojure:clojure:jar:1.11.1

the lead error causing the above trace is the following:

Caused by: org.apache.http.conn.ConnectTimeoutException: Connect to repo1.maven.org:443 [repo1.maven.org/151.101.60.209] failed: Connect timed out

Running clj -Sforce after removing the .m2 dependencies yields the same result. Checking with other tools it seems that https://repo1.maven.org/maven2 is not reachable. I can't confirm if it is unreachable for others outside of my location. However the fact that removing and force-reinstalling deps on my mac worked tells me that something can be done to reoslve the issue. just not sure what.

Any help appreciated.

Good day, I have exactly the same problem with  a Clojure installation on RHEL 8.7
$ clj
Error building classpath. Failed to read artifact descriptor for org.clojure:clojure:jar:1.11.1

My installation is behind a Firefall, we have the http_proxy and https_proxy global variables set, but probably we are missing the permissions for the program to go out in search of the componentes that he/she/it needs.

Does someone know what external pages needs clojure to run, to include them in the proxy permissions.?

Thank you in advance.

P.S  We have an OpenShift installation, and RedHat give to us the complete list of pages that we need to include in the proxy permissions to have a  cluster running behind the proxy and firewall.

Not really sure what to suggest ... seems like a networking issue on your machine?
