Working with multi-project builds


Let's start with a simple multi-project structure. We have a root project called garden with two other projects, tree and flower. The project structure is as follows:

└── garden
    ├── flower 
    └── tree 

We learn how we can invoke tasks in a multi-project build as follows:

  1. We will add a new printInfo task to each of these projects. The task will print the name of the project to System.out. We must add a build.gradle file to each project with the following contents:

            task printInfo << { 
                println "This is ${project.name}" 
           } 
    
  2. To execute the task for each project, we must first enter the correct directory and then invoke the task with Gradle. We can also run build.gradle for a specific project with the -b argument of Gradle. We will get the following output if we run the printInfo task for each project:

    garden $ gradle -q printInfo
    This is garden
    garden $ cd tree
    tree $ gradle -q printInfo
    This tree
    tree $ cd ..
    garden $ gradle...
