#!/bin/bash
# Rultor release versioning script for Maven projects..
#
# It looks for the project’s version, which MUST respect the pattern
# [0-9]*\.[0-9]*\.[0-9]*-SNAPSHOT.
#
# What it does: updates the pom.xml version of the project according to
# the variable ${tag} provided to rultor. Specifically, it increments the
# 3rd digit and adds '-SNAPSHOT' to it.
#
# IMPORTANT:
#     the given tag has to contain 3 numbers separated by dots!
#
#     e.g. tag = 1.0.1 or tag = 3.2.53 will result in new versions of 1.0.2-SNAPSHOT
#     or 3.2.54-SNAPSHOT
