503s when trying to download plugins from the latest I-Build

Summary

I am running mvn install -pl org.eclipse.jdt.core.compiler.batch,org.eclipse.jdt.core,,org.eclipse.jdt.core.tests.compiler,org.eclipse.jdt.core.tests.model,org.eclipse.jdt.core.javac -DskipTests in the following project: https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator with an empty maven repo. This downloads a bunch of dependencies from the following p2 repo: https://download.eclipse.org/eclipse/updates/4.36-I-builds/I20250304-1800

While attempting downloading these dependencies, Maven reports that the download of one of the plugins failed with the error code 503. The specific jar that causes the failure is different each time.

Steps to reproduce

1. Clone https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator
2. Make a directory to use as an empty Maven repo (eg. myEmptyRepo)
3. mvn install -pl org.eclipse.jdt.core.compiler.batch,org.eclipse.jdt.core,,org.eclipse.jdt.core.tests.compiler,org.eclipse.jdt.core.tests.model,org.eclipse.jdt.core.javac -DskipTests -Dmaven.repo.local=myEmptyRepo (replace myEmptyRepo with the path to the empty directory you made in step 2)

What is the current bug behavior?

Build fails due to a 503 when downloading dependency plugins from the I-Builds P2 repo

What is the expected correct behavior?

Installs the code into the temporary Maven repository

Impact

Preventing me from running the tests locally to check my work, so I'll have to find some other project to work on in the mean time.

Also in CI builds: https://ci.eclipse.org/ls/job/jdt-core-incubator/job/PR-1301/1/console

Thank you for reporting this. We are investigating.

mentioned in issue #5721 (closed)

Looks like one of the backends crashed and didn't recover. I've gotten it back on it's feet so this should be fixed.

Seems to working well now

We've added a configuration to make a request to a different node if one node is responding with a 503, so the problem is fixed, and the underlying service is now a bit more robust.
