[jbosstools-issues] [JBoss JIRA] (JBIDE-13671) Replace build timestamp in qualifier by last-mod-timestamp from git

[Mickael Istria (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13248316#comment-13248316 ] 

Mickael Istria commented on JBIDE-13671:
----------------------------------------

{quote}1. Enable 'compare with baselines' for every build's previous /latest/ CI, to ensure that a TP change shows an API break, hopefully{quote}
Reading carefully https://wiki.eclipse.org/Tycho/Reproducible_Version_Qualifiers:
{quote}If baseline repositories contain artifacts with the same id and version but different contents, depending on <baselineMode> configuration parameter the build will either fail or generated artifacts will be replaced with baseline version. {quote}
So it seems like the comparison with baseline and failure in case of duplicate is included in the tycho-packaging-plugin. So we only need to enable baseline replacement in tycho-packaging-plugin using the previous build as a baseline. Note that the tycho-packaging-plugin baseline can be enabled independently of the jgit-timestamp-buildqualifier thing.
