So far all the settings are explicitly set in setDefaultSettings() and setJavaConventionsSettings(), I'd keep that way unless there's a good reason not to.

Hi @HannesWell
Is it okay to ignore this build failure and merge ?

I'm not completly sure as I don't know that project very well and looking at it's pom it seems to be a bit special. So I cannot really tell if this is common issue. Maybe @iloveeclipse can help here as he created large parts of that projects build config?

Nevertheless I see a similar failure on the master branch of jdt.core and it looks again similar to the build problems I saw in the release preparation PR (but there I assumed it's a usual hick-up that can be investigated later):

• Prepare 4.38 development #4364

And last but not least I see the following error currently in the eclipse.platform.releng.aggregator master build:
[ERROR] Failed to execute goal org.eclipse.tycho.extras:tycho-p2-extras-plugin:5.0.0:compare-version-with-baselines (compare-attached-artifacts-with-release) on project org.eclipse.jdt.core: Only qualifier changed for (org.eclipse.jdt.core/3.43.0.v20250908-1850). Expected to have bigger x.y.z than what is available in baseline (3.43.0.v20250820-1501) -> [Help 1]

This is not the very same eclipse-project/tycho-module but at least also from this repo and I wonder if this is related.

So TL;DR: I'm not sure yet, but I lean towards not ok.
