Getting Started with the Wowza Gradle Plugin

Now that your environment is set up, it’s time to dive into the Wowza Gradle Plugin itself. This section will guide you through the process of creating a simple Wowza module project, configuring the plugin, and building your project.

1. Creating a Wowza Module Project

The first step is to create a new Wowza module project. If you’re starting from scratch, follow these steps:

• Step 1: Create a new directory for your project:

  mkdir my-wowza-project
  cd my-wowza-project

• Step 2: Initialize a new Gradle project within this directory:

  gradle init

• Step 3: Choose the project type (e.g., a Java application) and provide the necessary details.

2. Configuring the Wowza Gradle Plugin

Once your project is set up, you’ll need to configure the Wowza Gradle Plugin by modifying your build.gradle file. Here’s how you can do it:

• Step 1: Open the build.gradle file in your project directory.
• Step 2: Apply the Wowza Gradle Plugin by adding the following line at the top of the file:

  plugins {
      id 'com.wowza.gradle.plugin' version '1.0.0'
  }

• Step 3: Configure the plugin by adding a wowza block to your build.gradle file. Here’s an example configuration:

  wowza {
      engineHome = '/path/to/your/wowza-installation'
      moduleName = 'MyWowzaModule'
      moduleDescription = 'A custom Wowza module'
  }

3. Building and Deploying Your Module

With your project and plugin configured, you can now build and deploy your Wowza module. The Wowza Gradle Plugin provides several tasks that automate these processes:

• Build the Project: Compile your code and package it into a JAR file using the following command:

  gradle build

• Deploy to Wowza Streaming Engine: Deploy the built module to your Wowza Streaming Engine instance with:

  gradle deployWowzaModule

4. Testing and Debugging

Testing and debugging are critical steps in the development process. The Wowza Gradle Plugin includes tasks that make it easier to test your modules:

• Run Unit Tests: Execute unit tests to ensure your code functions as expected:

  gradle test

• Debugging: If you encounter issues, use Gradle’s logging and debugging features to troubleshoot. You can increase the logging level with:

  gradle build --info

Advanced Features of the Wowza Gradle Plugin

The Wowza Gradle Plugin offers several advanced features that cater to more complex development scenarios. Understanding and utilizing these features can help you optimize your workflow and manage larger projects effectively.

1. Custom Task Definitions

Gradle’s flexibility allows you to define custom tasks tailored to your specific needs. For example, you might want to automate the process of clearing logs before building:

task clearLogs(type: Delete) {
    delete fileTree(dir: "${wowza.engineHome}/logs", include: '*.log')
}

2. Multi-Module Projects

For large-scale applications, you might have multiple Wowza modules that need to be built and deployed together. The Wowza Gradle Plugin supports multi-module projects, enabling you to manage them within a single Gradle build:

• Step 1: Structure your project with a root directory containing subdirectories for each module.
• Step 2: In the root build.gradle file, include the subprojects:

  subprojects {
      apply plugin: 'com.wowza.gradle.plugin'
  }

• Step 3: Build and deploy all modules together:

  gradle build
  gradle deployWowzaModule

3. Continuous Integration (CI) with Wowza Gradle Plugin

Integrating the Wowza Gradle Plugin with your CI/CD pipeline can significantly enhance your development workflow. Here’s how you can set it up with popular CI tools:

Using Jenkins
