[jira] [Created] (ZOOKEEPER-3744) Make build reproducible

Erik created ZOOKEEPER-3744:
-------------------------------

             Summary: Make build reproducible
                 Key: ZOOKEEPER-3744
                 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3744
             Project: ZooKeeper
          Issue Type: Wish
            Reporter: Erik
         Attachments: diffoscope.txt

Maven has added built-in support for creating reproducible builds. See [https://maven.apache.org/guides/mini/guide-reproducible-builds.html.] The Zookeeper build is very close to being reproducible as is and would only require minor changes to get all the way there:
 # Add the property project.build.outputTimestamp to the top level project object model.
 # Upgrade the maven-jar-plugin to 3.2.0.
 # Enable notimestamp for the maven-javadoc-plugin.
 # Figure out to do with the classes Version, VersionInfo and VersionInfoMain.

I did the first three and attached is the resulting diffoscope log for .\zookeeper-assembly\target\apache-zookeeper-3.7.0-SNAPSHOT-bin.tar.gz.

For 1 and 4 I suggest using a Git commit timestamp.

For 3 I believe there could be a fix in the upcoming 3.2.0 version of the maven-javadoc-plugin that would make notimestamp unnecessary. See https://issues.apache.org/jira/browse/MJAVADOC-627.
