very good question: this was a key question to me, that lead me to the PoC to test and see this PoC showed a basic fact: a POM will inherit the value from his parent
Then once a parent POM has a "reproducibility" timestamp, child POMs inherit reproducible configuration, and can eventually override value I imagine that we'll do a maven-release-plugin feature to update the value to match release timestamp But we can start by updating the value by hand if we want to have a value that has a better meaning that the inherited one Regards, Hervé Le samedi 28 septembre 2019, 22:52:04 CEST Enrico Olivelli a écrit : > Hervé > When will you set this value?
