Re: [tycho-user] compare-version-with-baselines

[Vincent GUIGNOT <Vincent.GUIGNOT@xxxxxxxxxxxx>]

Hello,

 

I’ve followed the  https://wiki.eclipse.org/Tycho/Reproducible_Version_Qualifiers  advice , and it works. Thanks .

After replacing or not replacing the artifact, tycho  compare with the baseline and find or not some errors.

But sometimes, The  artifact is replaced, and the comparaison failed :

Duplicate version but different content found for (wxwxw). Also exists in baseline, but its content is different.

 

After erasing  the .m2/repository , and build again the error disapears. I’supposed the artifacts are cached inside the .m2/repository, but I don’t understand why it fails

 

 

Regards

 

Vincent

Hi Vincent,

If I unzip the 2 artefacts, content are identiquals. If I compare the artefacts themself, there are differents, because the date of the zipped files are not the same.

As a reference, Platform uses a mechanism to replace the new artifact with the "baseline" one in case there is no change. So that allows to have exactly the same binary. See https://wiki.eclipse.org/Tycho/Reproducible_Version_Qualifiers .
However, I believe your user story is an interesting one that compare-with-baseline plugin should be able to handle. For example, it could allow multiple strategies for comparison, including one that would compare content instead of byte-to-byte to better handle your use-case-case, and user could select a strategy ("byte-equality", "archive-content-equality"...) via pom.xml. Please open a Bugzilla request for that.

Cheers,
