Jonathan Coveney updated PIG-2380:
----------------------------------
Attachment: PIG2380_1.patch
I changed the logic so it will just warn the user if the manifest isn't
available. This has the beneficial side effect (which you predicted, Gianmarco)
of letting people run -h without the Pig jar present. I rediffed against an
updated branch and successfully applied to a clean branch, but let me know if
you hit an issue.
I ran ant test-commit just to be thorough: no issues :)

> Currently, there is no clean way to get version information (short of trying
> to instantiate a class that only exists in the version you want and catching
> an exception, or something like that). This patch exposes major, minor,
> patch, svn revision, and build time (basically, all of the pieces of the
> current version).
> Example:
> {code}
> import org.apache.pig.Main;
> public class Thing {
> public static void main(String[] args) {
> System.out.println(Main.getMajorVersion());
> System.out.println(Main.getMinorVersion());
> System.out.println(Main.getPatchVersion());
> System.out.println(Main.getSvnRevision());
> System.out.println(Main.getBuildTime());
> }
> }
> {code}

> {code}
> I've run ant test-commit, but not ant test. This can easily be ported to old
> version, but I only tested it against trunk.
