Installing and Configuring the Wowza Gradle Plugin: A Step-by-Step Guide

Step 1: Download and Install Gradle

To begin, install Gradle on your system using the appropriate command for your operating system:

• MacOS: brew install gradle
• Windows (using Chocolatey): choco install gradle
• Linux: sudo apt-get install gradle

Step 2: Integrate the Wowza Gradle Plugin

Add the Wowza Gradle Plugin to your build.gradle file by including the following code:

groovy

Copy code

plugins {

    id ‘com.wowza.gradle-plugin’ version ‘1.0.0’

}

 

repositories {

    mavenCentral()

}

 

dependencies {

    compile ‘com.wowza:wowza-gradle-plugin:1.0.0’

}

 

Step 3: Configure Your Build

Customize your build.gradle file to include Wowza-specific settings, such as the server location and application name:

groovy

Copy code

wowza {

    serverHome = file(‘/path/to/wowza’)

    applicationName = ‘myWowzaApp’

}

 

Step 4: Execute the Build Process

Run the build process using the following command:

bash

Copy code

gradle build

 

Managing Dependency Challenges

Overhead of WSE Dependencies

A standard installation of Wowza Streaming Engine (WSE) version 4.8.17 includes nearly 140 jar files in the lib folder, all of which are added to the classpath when your module is loaded. Testing and ensuring compatibility of commercial modules across various WSE versions can be challenging.

The jar files in WSE are divided into two categories: WSE API (e.g., wse-*.jar) and third-party dependencies. Initially, we tracked the versions of libraries our modules used to ensure compatibility with Wowza’s shipped versions. Libraries frequently overlapping with Wowza’s include Google Gson, Apache HttpClient, and AWS SDK. Managing this required creating branches of our code tailored to compatible Wowza versions, leading to significant administrative overhead.

Specifying Wowza Version and Automating Dependency Management

To address dependency management, we aimed to specify the Wowza version for building and testing modules as a parameter in our build process. The solution involved establishing a private Maven repository and publishing the required dependencies as a bill-of-materials (BOM). A Groovy script was developed to automate the publication of these dependencies shortly after each Wowza Streaming Engine release.

This approach streamlined dependency management, ensuring compatibility with various versions of Wowza Streaming Engine.

Managing Shared and Shaded Dependencies

When working with third-party dependencies, such as Gson for JSON handling, it is essential to manage these libraries carefully to avoid conflicts. In a Wowza Streaming Engine (WSE) environment, dependencies are often shared across modules, which can lead to issues if different modules require different versions of the same library.

Shared Dependencies

Shared dependencies are libraries used across multiple modules. In the context of WSE, these shared libraries must be compatible with all modules to ensure smooth operation. Here are some strategies for managing shared dependencies:

• Dependency Management Tools: Use tools like Maven or Gradle to manage versions and ensure compatibility across modules. Define dependencies in a central location (e.g., a BOM file) and apply versioning consistently.
• Version Alignment: Align the versions of shared libraries with those used by Wowza to prevent conflicts. Regularly update and test these dependencies to ensure compatibility with new Wowza releases.
• Conflict Resolution: When conflicts arise, use dependency mediation to resolve version discrepancies. Tools like Gradle’s resolution strategy can help force a specific version of a library across modules.

Shaded Dependencies

Shaded dependencies are libraries bundled into the final artifact, which helps avoid conflicts with other libraries. This approach is particularly useful for isolating dependencies and preventing classpath issues. Here’s how to manage shaded dependencies:

• Jar Shading: Use Gradle’s Shadow plugin or similar tools to create an uber-jar that includes all necessary dependencies. This isolates your module from potential conflicts with other modules in the WSE environment.
• Package Relocation: Relocate package names of shaded dependencies to avoid conflicts with existing libraries. This can be achieved by configuring shading plugins to change the package structure of the included libraries.
• Testing: Thoroughly test shaded dependencies to ensure they do not interfere with other parts of the application. Pay attention to classpath issues and library conflicts during integration testing.

Troubleshooting Common Issues

Dependency Conflicts

Dependency conflicts can arise when multiple modules or libraries require different versions of the same dependency. Common symptoms include runtime errors, class not found exceptions, and inconsistent behavior.

Solutions:

• Dependency Resolution: Use Gradle’s resolution strategies to enforce specific versions of conflicting libraries.
• Dependency Exclusions: Exclude conflicting transitive dependencies from specific modules.
• Dependency Analysis: Utilize tools like Gradle’s dependency insight to identify and resolve conflicts.

Build Failures

Build failures can occur due to configuration issues, missing dependencies, or incompatible versions.

Solutions:

• Configuration Review: Review and correct build scripts and configurations to ensure they align with project requirements.
• Dependency Check: Verify that all required dependencies are correctly declared and available.
• Logs and Errors: Analyze build logs and error messages to identify the root cause of failures.

Integration Issues

Integration issues may arise when incorporating the Wowza Gradle Plugin into existing projects or workflows.

Solutions:

• Documentation Review: Refer to the official Wowza Gradle Plugin documentation for integration guidance and best practices.
• Community Support: Seek assistance from the Wowza community or support forums for troubleshooting and advice.
• Testing: Conduct thorough testing in a staging environment before deploying changes to production.
