How to Ensure Gradle Calls Default Tasks of Other Modules in Your Project

When working with Gradle, developers often encounter challenges when one module does not automatically execute the default tasks of another. This issue can halt your development process and lead to confusion. In this guide, we will explore a common project structure and provide a solution to ensure that default tasks from other modules are invoked correctly when building. Let's dive into the details!

Understanding the Problem

Consider a typical project structure like this:

In your settings.gradle, you have included both projects:

Default Tasks in Project-1

In project-1/build.gradle, you have defined default tasks to be executed:

Here, task3 is essential as it copies the build file of project-1 to a directory in project-2. This is a necessary step because project-2 relies on these files for its build process. However, when you build project-2, it does not trigger the default tasks of project-1, which leads to build failures.

The Solution

To solve this issue, we can leverage Gradle’s task dependencies. By explicitly setting dependencies between tasks in project-1, we can ensure that when project-2 is built, all required tasks in project-1 are executed first. Here’s how to do it:

Step-by-Step Fix

Step 1: Update project-1/build.gradle

Modify your build.gradle file in project-1 to explicitly define task dependencies as follows:

This change creates a clear dependency chain where:

compileJava will run task3

task3 will run task2

task2 will run task1

By defining these dependencies, Gradle understands the order in which tasks should be executed.

Step 2: Adjust project-2/build.gradle

Now, in your project-2/build.gradle, change the dependencies section to:

What This Achieves

By linking project-2 to project-1 directly, you allow Gradle to know that when you build project-2, it should also build project-1 along with all its defined tasks, including task1, task2, and task3. This ensures that everything is prepared properly prior to the build of project-2.

Conclusion

By implementing the above modifications, you can seamlessly integrate the build processes between multiple Gradle modules. This not only saves time but also minimizes errors caused by missing dependencies. With a structured approach, Gradle can handle complex project structures with ease, allowing you to focus on your development rather than troubleshooting build issues.

Now you can confidently work on your multi-module Gradle projects, knowing that your default tasks will always be executed as intended.
