Q:

Gradle Vs Maven

1 Answer

Nov 11, 2019

The following is a summary of the major differences between Gradle and Apache Maven:

Flexibility: Google chose Gradle as the official build tool for Android; not because build

scripts are code, but because Gradle is modeled in a way that is extensible in the most

fundamental ways.

Both Gradle and Maven provide convention over configuration. However, Maven provides a

very rigid model that makes customization tedious and sometimes impossible.

While this can make it easier to understand any given Maven build, it also makes it

unsuitable for many automation problems. Gradle, on the other hand, is built with an

empowered and responsible user in mind.

Performance

Both Gradle and Maven employ some form of parallel project building and parallel

dependency resolution. The biggest differences are Gradle's mechanisms for work

avoidance and incrementally. Following features make Gradle much faster than Maven:

Incrementally:Gradle avoids work by tracking input and output of tasks and only

running what is necessary.

Build Cache:Reuses the build outputs of any other Gradle build with the same

inputs.

Gradle Daemon:A long-lived process that keeps build information "hot" in memory.

User Experience

Maven's has a very good support for various IDE's. Gradle's IDE support continues to

improve quickly but is not great as of Maven. 6/71

Although IDEs are important, a large number of users prefer to execute build operations

through a command-line interface. Gradle provides a modern CLI that has discoverability

features like `gradle tasks`, as well as improved logging and command-line completion.

Dependency Management

Both build systems provide built-in capability to resolve dependencies from configurable

repositories. Both are able to cache dependencies locally and download them in parallel.

As a library consumer, Maven allows one to override a dependency, but only by version.

Gradle provides customizable dependency selection and substitution rules that can be

declared once and handle unwanted dependencies project-wide. This substitution

mechanism enables Gradle to build multiple source projects together to create composite

builds.

Maven has few, built-in dependency scopes, which forces awkward module architectures in

common scenarios like using test fixtures or code generation. There is no separation

between unit and integration tests, for example. Gradle allows custom dependency scopes,

which provides better-modeled and faster builds.
