#!/bin/bash -x
# Generates the 'source tarball' for JDK 8 projects.
#
# Example:
# When used from local repo set REPO_ROOT pointing to file:// wth your repo
# if your local repo follows upstream forests conventions, you may be enough by setting OPENJDK_URL
# if you wont to use local copy of patch PR2126 set path to it to PR2126 variable
#
# In any case you have to set PROJECT_NAME REPO_NAME and VERSION. eg:
# PROJECT_NAME=jdk8u   OR   aarch64-port 
# REPO_NAME=jdk8u60    OR   jdk8u60 
# VERSION=jdk8u60-b27  OR aarch64-jdk8u65-b17 OR for head, keyword 'tip' should do the job there
# 
# They are used to create correct name and are used in construction of sources url (unless REPO_ROOT is set)

# This script creates a single source tarball out of the repository
# based on the given tag and removes code not allowed in fedora/rhel. For
# consistency, the source tarball will always contain 'openjdk' as the top
# level folder, name is created, based on parameter
#
