Performing Android Release with Maven

perform_release.sh

# Create a release branch
RELEASE_VERSION=`mvn help:evaluate -Dexpression=project.version | grep -v INFO | grep SNAPSHOT | cut -d '-' -f 1`
git checkout -b release/$RELEASE_VERSION

# Prepare a release (Note we do not push any tags just yet)
mvn -B release:prepare -DpushChanges=false -DremoteTagging=false -DscmCommentPrefix= -P release

# The project has been built and now we want to deploy
# but we need to ensure our manifest stays in line with our releases
git reset HEAD~1
git checkout AndroidManifest.xml
git stash

# Deploy the release artifact
mvn deploy -P release

# At this point the manifest is correct so we want it
# in the git history
git add AndroidManifest.xml
git commit --amend --no-edit

# Cleanup and run a build with latest dev commit
# to bring manifest back up to date
git clean -f
git stash pop
mvn clean test
git add AndroidManifest.xml pom.xml
git commit -m 'kicking off next development iteration'

# I wish the release plugin made a little sense but 
# we need to delete the tag it created because
# I'd rather tag in master branch
git tag -d "v$RELEASE_VERSION"

# Merge latest development iteration
git checkout development
git merge --no-ff -m "merging in next development iteration" -X theirs release/$RELEASE_VERSION

# Merge the release commit to master (note the ~1 to indicate we want the
# second to last commit)
git checkout master
git merge --no-ff -m "$RELEASE_VERSION release" -X theirs release/$RELEASE_VERSION~1

# Tag the release on master branch
git tag -a "v$RELEASE_VERSION" -m "$RELEASE_VERSION release"

# Push all updates to remote repos
git push --all && git push --tags
