#!/bin/bash
#Usage
#First parameter is the version name either release or snapshot works
#if it is release version, script create and checkout a branch, update version, commit, tag and push the script
# ./ams_release.sh 1.6.1
#if it is release version with branch parameter, script create & checkout a branch and push the 
#./ams_release.sh 1.6.1 branch
#if it is a snapshot version, it updates the version, commits and pushes . After that it should be merged with master
#./ams_release.sh 1.6.2-SNAPSHOT

#Future work: Deploying to maven central takes about 2-3 hours so that it blocks Ant-Media-Server to pass the test.
#another solution we may add sonatype as release repo
