[jbosstools-issues] [JBoss JIRA] (JBIDE-13671) parent pom should use last-mod-timestamp from git for a plugin/feature instead of current timestamp when building

[Nick Boldt (JIRA)]

    [ https://issues.jboss.org/browse/JBIDE-13671?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12759155#comment-12759155 ] 

Nick Boldt commented on JBIDE-13671:
------------------------------------

One proposal that might solve the question of "was this built locally" or "was this built in Jenkins" and ensure that locally built always has a newer timestamp than that in Jenkins CI:

a) profile for Jenkins needs to be updated to use "-CI" instead of "-B${BUILD_NUMBER}"
b) profile for Jenkins uses jgit timestamp provider

c) default profile omits the "-CI" and "-Bxxxx" suffix, as it does today
d) default profile uses the default timestamp provider, as it does today

Therefore the change proposed should now ONLY be made to the existing jenkins profile, and PR https://github.com/jbosstools/jbosstools-build/pull/72 should be rejected.
