Gradle vs gulp: What are the differences?

1. Key Difference 1: Build Automation System: Gradle is a build automation system that uses a Groovy-based domain-specific language (DSL) while Gulp is a task runner built on top of Node.js. Gradle provides a powerful and flexible build system with a declarative syntax that allows developers to define complex build processes easily. On the other hand, Gulp leverages JavaScript and its ecosystem to automate repetitive tasks during development, such as minification, compilation, and testing.
2. Key Difference 2: Configuration: Gradle uses a configuration file called build.gradle which is written in Groovy or Kotlin, whereas Gulp uses a JavaScript file called gulpfile.js to define tasks and their configurations. Gradle's configuration file supports a more expressive and concise syntax, while Gulp's configuration file is written in JavaScript, providing flexibility but with a potentially steeper learning curve for developers new to JavaScript.
3. Key Difference 3: Plugin Ecosystem: Gradle has a rich ecosystem of plugins, both official and community-supported, that provide additional functionality and integration with various tools and frameworks. These plugins can be easily integrated and maintained through Gradle's dependencies management. Gulp also has a wide range of plugins available through the Node Package Manager (NPM) registry, allowing developers to choose from a large number of community-maintained packages to enhance their build and workflow automation.
4. Key Difference 4: Task Execution Model: Gradle has a highly parallelized task execution model, which means tasks can be executed in parallel, resulting in efficient build times. Gulp, on the other hand, follows a stream-based task execution model, where tasks are executed sequentially and can process data as streams, allowing developers to create efficient and performant build pipelines.
5. Key Difference 5: Language Compatibility: Gradle supports multiple JVM (Java Virtual Machine) languages like Java, Groovy, and Kotlin, making it suitable for building projects written in these languages. Gulp, being based on Node.js, is primarily used for JavaScript-based projects, but it can also be used to automate tasks in other languages as long as they can be executed through Node.js.
6. Key Difference 6: Community and Adoption: Gradle has been widely adopted and is the official build tool for Android development, making it the go-to choice for many Android developers. It also has a strong community with extensive documentation and support. Gulp, while also having significant popularity, particularly in the JavaScript ecosystem, may have a smaller community compared to Gradle, resulting in potentially fewer resources and support for certain use cases.

In Summary, Gradle and Gulp differ in their build automation systems, configuration files, plugin ecosystems, task execution models, language compatibility, and community adoption.
