#!/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 and BE THE FIRST MATCH in pom.xml
#
# 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

#Right after the project's <version> tag there has to be the comment <!--rrv-sed-flag--> which simplifies the sed regex bellow. 
#If the flag comment wouldn't be there, we'd have to write a more complicated regex to catch the artifactif from a row up.
#This is because only a regex for version tag would change all the matching version tags in the file.
