To use this code, you need to have the file build.number containging:<\/p>\n

Add these three targets to your ant script.\u00a0 Put a “depends” to “setBuildNumber” at invocation of\u00a0your ant\u00a0script.\u00a0 Depending on what you want to do, you’ll set different vars on the way in as follows:<\/p>\n

\nTo move to the next major build number:

\nTo move to the next minor build number:

\nTo move to the next hotfix build number:
