Simple but probably
wrong.

The error is:
org.eclipse.ltk.core.refactoring:
Version have moved backwards for (org.eclipse.ltk.core.refactoring/3.10.100.v20190329-1313).
Baseline has 3.10.100.v20190510-0840) with delta: 0.0.0

The version in
the baseline is correct and it is the same version we have in our latest
build. The latest build also does not report such an error. There was no
change yet in that bundle for 4.13.

As we can see,
the version in the Jenkins build has a lower qualifier than in the baseline.
This indicates a problem with the build on Jenkins. Maybe the date/clock
got somehow changed/corrupted?

Some builds before,
it also failed for that bundle but with another strange version in the
Jenkins build: v20190618-2045

I've retriggered
the build but no luck.

Maybe is related
https://bugs.eclipse.org/547925?

Sravan, please
have a look.

Hi,

It means that the version in baseline
seems newer than the version in current build, which isn't something desired.

I think this case is a consequence of
a small change in parent pon to ignore .settings changes in qualifier computation
as most of those changes don't cascade to binary change and the compare-with-baselines
mojo detects issues in case binaries are modified.
This can cause an issue for projects
whose last committed change only affects .settings because newer build
would compute an older qualifier forthe same module. Although the probability
of it happening was low, it was not 0 and it looks like you found an occurrence
of the issue. The simplest remediation is to bump with +0.0.100 here.

What does that mean?
