# Generates the 'source tarball' for JDK projects.
#
# Example 1:
# When used from local repo set REPO_ROOT pointing to file:// with your repo.
# If your local repo follows upstream forests conventions, it may be enough to
# set OPENJDK_URL.
#
# Example 2:
# This will read the OpenJDK feature version from the spec file, then create a
# tarball from the most recent tag for that version in the upstream Git
# repository.
#
# $ OPENJDK_LATEST=1 ./generate_source_tarball.sh
# [...]
# Tarball is: temp-generated-source-tarball-ujD/openjdk-17.0.10+6-ea.tar.xz
#
# Unless you use OPENJDK_LATEST, you have to set PROJECT_NAME, REPO_NAME and
# VERSION, e.g.:
#
# PROJECT_NAME=openjdk
# REPO_NAME=jdk17u
# VERSION=jdk-17.0.10+7
#
# or to e.g., prepare systemtap, icedtea7's jstack and other tapsets:
#
# VERSION=6327cf1cea9e
# REPO_NAME=icedtea7-2.6
# PROJECT_NAME=release
# OPENJDK_URL=http://icedtea.classpath.org/hg/
# TO_COMPRESS="*/tapset"
#
# 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.
