* Enable Java 11 features As of this commit Java 11 must be used to build. The generated bytecode is still at Java 8 due to App Engine task queue limit. Also fixed a bug where the included google-java-format jar file is not used, requiring the user to install it separately. See: https://cloud.google.com/appengine/docs/standard/java/taskqueue/push

# This script applies Google Java format to modified regions in Java source
|
|
# files in a Git repository. It assumes that the repository has a 'master'
|
|
# branch that is only used for merging and is never directly worked on.
|
|
#
|
|
# If invoked on the master branch, this script will format the modified lines
|
|
# relative to HEAD. Otherwise, it uses the
|
|
# 'git merge-base --fork-point origin/master' command to find the latest
|
|
# fork point from origin/master, and formats the modified lines between
|
|
# the fork point and the HEAD of the current branch.
|
|
#
|
|
# Background: existing code base does not conform to Google Java format. Since
|
|
# the team wants to keep the 'blame' feature (find last modifier of a line)
|
|
# usable, we do not want to reformat existing code.
