# Handing license header files

# The license is defined in the gsf-build-tools project. If the header needs to change it needs to be done there
# The LicenseHeader.txt does not contain the copyright statement, as this can be different for each file. This file is used
# to trick the license plugin and not barf over different copyright statements. 
# you can issue mvn license:format -Dcompany="My Corporation" to add header files with a copyright statement to all files that do not have a license header.

# quick check if a copyright statement is present
# find . -name '*.java'  ! -exec egrep -q 'Copyright .* All Rights Reserved' {} \; -ls

# Site Update instructions (tested for version 12.0.1 on Oct 24, 2016 by Tony Field)
# - update poms to new release version for all modules (gst-foundation, gsf-build-tools, gsf-core, gsf-legacy)
# - update site.xml to link to new "previous version" site
# - update the download.apt.vm page to link to the new download and update prior versions
# - update documentation as needed
# - run this script to build the package (sh package.sh)
# - validate build
# - commit poms & site
# - issue pull request into version trunk (e.g. gst-foundation-12)
# - save full site zip from target folder
# - checkout gh-pages branch
# - add new folder to releases directory for new version (e.g. gsf-12.0.1)
# - extract full site zip from gh-pages branch
# - place content from teh site folder into the release folder in the gh-pages checkout
# - edit index.html to redirect users to the new version (i.e. update the meta refresh tag)
# - commit the gh-pages changes
# - verify the site - navigate to gst-foundation.org and you should be directed to the new version
# - if your release is the latest major version, (i.e. 12 not 11 or 1) then issue a pull request to pull your changes from the version trunk into the master branch, so that the master branch remains the most stable release
# - checkout the version branch again
# - update the pom files to reflect the next minor/patch version's snapshot label (e.g. 12.0.2-SNAPSHOT)
# - if using artifactory or another maven repository, be sure to upload the gsf-parent pom.xml file, gsf-core-x.jar and gsf-legacy-x.jar to the repo.
