Hello!

I have a bug and submitted a patch, but it is stuck in a stovepipe in a larger merge-train headed for Java 11:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=575629
https://git.eclipse.org/r/c/jgit/jgit/+/185277

I need this patch urgently, so I am aiming to fork and build a feature patch. For this, I need to replicate the JGit build infrastructure that lives somewhere on Eclipse:

https://ci.eclipse.org/jgit/job/stable/job/jgit.gerrit-pipeline/5407/

Is there a reproducible description (container-based), or is this the only location where I can faithfully build JGit (I-am-a-snowflake build server)?

I have set up a bazel, as I found a bazel file and I found that there is a maven build, but it fails as it references some natives, and there is no information what the root call to maven actually is.

Thanks for any advice. Feels a bit like developing on big iron. ;)

Quick update, I checked the CI descriptor in the mvn pom as well, it points to ci.eclipse.org, which mentions you should use a platform pipeline file, but it is not visible, and not checked into the repo. So no dice here either. :(

JGit has 2 builds, I recommend to use the Maven build. The bazel build is mainly used to build Gerrit Code Review which includes jgit as a submodule.
The contributor guide describes how to run the build: https://wiki.eclipse.org/EGit/Contributor_Guide#JGit_2

The CI job depends on the infrastructure provided by Eclipse which runs Jenkins on Kubernetes so I am not sure that's a good fit to replicate this setup elsewhere.
We plan to move the pipeline definition to a separate repository like we did for EGit. Someone needs to find time to work on that.

My change series switching to Java 11 waits for reviewers and I don't want to self-approve them.
It seems the other committers are currently busy or not available.
If you have time and want help you may consider to review these changes.

Thanks. If this speeds things up, I am happy to review you changes. Please note I am not an approved committer on JGit/EGit. I assume I would find review aim/standards in the same location as the build instructions?
