Automating synchronization when developping several libraries and projects at the same time

Question

I want incremental updates of my library files to immediately be applied in all of my projects using them, without having to perform an extra step every time for every one of my projects (such as updating a sub-repository or a JAR file).

Answer 1

With the library folder in the LIBS_DIR environment variable:

// settings.gradle
include ':app', ':lib1', ':lib2'
project(':lib1').projectDir = new File(System.getenv('LIBS_DIR'), 'lib1')
project(':lib2').projectDir = new File(System.getenv('LIBS_DIR'), 'lib2')

‏‏‎

// build.gradle
...
dependencies {
    compile project(path: ':lib1')
    compile project(path: ':lib2')
}
