An example of building projects in a monorepo using Gradle Composite Builds that share a common buildSrc.

NOTE: After further investigation and attempts to make this work on a larger, more complex, project it appears that buildSrc on composite builds is not a fully supported feature at this time and YMMV with this approach. The good news is that according to the Gradle docs it appears that official support for this functionality is in the works.

The repository contains four projects each with their own Gradle configurations.

Projects A, B, and C have dependencies on one another:

[project-a] -- DEPENDS --> [project-b] -- DEPENDS --> [project-c]

Project D has no dependencies on the other projects:

[project-d]

All four projects also have access to the common buildSrc directory where they can get tasks and plugins that are shared amongst them.

Follow the steps below to run the example:

Run the following commands to build project-a:

1. Change the working directory to project-a:

    cd project-a
   

2. Run the following command to execute the hello task:

    ./gradlew hello
   

   If successful, you will see the following in the console:

    > Task :hello
    Hello from task :hello!
   

Run the following commands to build project-d:

1. Change the working directory to project-d:

    cd project-d
   

2. Run the following command to execute the hello task:

    ./gradlew hello
   

   If successful, you will see the following in the console:

    > Task :hello
    Hello from task :hello!
   

IntelliJ supports Gradle Composite Builds and will automatically open any included builds for a project.

To see this in action, open project-a in your IntelliJ IDE. You will notice that IntelliJ automatically opens project-b as well as the buildSrc project because they are both dependencies of the current project.
