DependencyConstraintHandler

A DependencyConstraintHandler is used to declare dependency constraints.

Dependency constraint notations

There are several supported dependency constraint notations. These are described below. For each dependency constraint declared this way, a DependencyConstraint object is created. You can use this object to query or further configure the dependency constraint.

You can also always add instances of DependencyConstraint directly:

Dependency constraints can also be declared with a org.gradle.api.provider.Provider that provides any of the other supported dependency constraint notations.

External dependencies

plugins {
    id("java-library")
}

dependencies {
    constraints {
        // Declaring constraints on module components
        // Coordinates are separated by a single colon -- group:name:version
        implementation("org.apache.commons:commons-lang3:3.17.0")
        testImplementation("org.mockito:mockito-core:5.18.0")
    }
}

Project dependencies

To add a project dependency constraint, you use the following notation:

configurationName(project(":some-project"))
