Expose version information more cleanly
---------------------------------------
Key: PIG-2380
URL: https://issues.apache.org/jira/browse/PIG-2380
Project: Pig
Issue Type: Improvement
Reporter: Jonathan Coveney
Assignee: Jonathan Coveney
Priority: Minor
Fix For: 0.11
Attachments: PIG2380.patch
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}
will return
{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.
