Multi-project Builds

1. Create settings.gradle

include ':microservices:product-service'
include ':microservices:review-service'
include ':microservices:recommendation-service'
include ':microservices:product-composite-service'

2. Copy the generated Gradle executable files from one of the projects

cp -r microservices/product-service/gradle .
cp microservices/product-service/gradlew .
cp microservices/product-service/gradlew.bat .
cp microservices/product-service/.gitignore .

3. Remove the generated Gradle executable files in each project

find microservices -depth -name "gradle" -exec rm -rfv "{}" \;
find microservices -depth -name "gradlew*" -exec rm -fv "{}" \;

4. Build

./gradlew build
