git clone https://github.com/Baseflow/PhotoView.git
cd PhotoView
git checkout 565505d
# use java 8
export ANDROID_HOME=$HOME/Library/Android/sdk
sed -i "s/version = '2.3.0'/version = '565505d5cb'/" photoview/build.gradle
./gradlew --no-daemon -Dmaven.repo.local=/PATH/TO/vault-android/app/libs publishToMavenLocal
