public interface DependencyHandler
A DependencyHandler is used to declare dependencies. Dependencies are grouped into
configurations (see Configuration).
To declare a specific dependency for a configuration you can use the following syntax:
dependencies {
configurationName dependencyNotation1, dependencyNotation2, ...
}
Example shows a basic way of declaring dependencies.
apply plugin: 'java'
//so that we can use 'compile', 'testCompile' for dependencies
dependencies {
//for dependencies found in artifact repositories you can use
//the group:name:version notation
compile 'commons-lang:commons-lang:2.6'
testCompile 'org.mockito:mockito:1.9.0-rc1'
//map-style notation:
compile group: 'com.google.code.guice', name: 'guice', version: '1.0'
//declaring arbitrary files as dependencies
compile files('hibernate.jar', 'libs/spring.jar')
//putting all jars from 'libs' onto compile classpath
compile fileTree('libs')
}
To do some advanced configuration on a dependency when it is declared, you can additionally pass a configuration closure:
dependencies {
configurationName(dependencyNotation){
configStatement1
configStatement2
}
}
Examples of advanced dependency declaration including:
ModuleDependency.exclude(java.util.Map).
apply plugin: 'java' //so that I can declare 'compile' dependencies
dependencies {
compile('org.hibernate:hibernate:3.1') {
//in case of versions conflict '3.1' version of hibernate wins:
force = true
//excluding a particular transitive dependency:
exclude module: 'cglib' //by artifact name
exclude group: 'org.jmock' //by group
exclude group: 'org.unwanted', module: 'iAmBuggy' //by both name and group
//disabling all transitive dependencies of this dependency
transitive = false
}
}
More examples of advanced configuration, useful when dependency module has multiple artifacts:
ModuleDependency.artifact(groovy.lang.Closure).
apply plugin: 'java' //so that I can declare 'compile' dependencies
dependencies {
//configuring dependency to specific configuration of the module
compile configuration: 'someConf', group: 'org.someOrg', name: 'someModule', version: '1.0'
//configuring dependency on 'someLib' module
compile(group: 'org.myorg', name: 'someLib', version:'1.0') {
//explicitly adding the dependency artifact:
artifact {
//useful when some artifact properties unconventional
name = 'someArtifact' //artifact name different than module name
extension = 'someExt'
type = 'someType'
classifier = 'someClassifier'
}
}
}
There are several supported dependency notations. These are described below. For each dependency declared this
way, a Dependency object is created. You can use this object to query or further configure the
dependency.
You can also always add instances of
Dependency directly:
configurationName <instance>
There are two notations supported for declaring a dependency on an external module. One is a string notation formatted this way:
configurationName "group:name:version:classifier@extension"
The other is a map notation:
configurationName group: group:, name: name, version: version, classifier:
classifier, ext: extension
In both notations, all properties, except name, are optional.
External dependencies are represented by a ExternalModuleDependency.
apply plugin: 'java'
//so that we can use 'compile', 'testCompile' for dependencies
dependencies {
//for dependencies found in artifact repositories you can use
//the string notation, e.g. group:name:version
compile 'commons-lang:commons-lang:2.6'
testCompile 'org.mockito:mockito:1.9.0-rc1'
//map notation:
compile group: 'com.google.code.guice', name: 'guice', version: '1.0'
}
To add a project dependency, you use the following notation:
configurationName project(':someProject')
The notation project(':projectA') is similar to the syntax you use
when configuring a projectA in a multi-module gradle project.
By default, when you declare dependency to projectA, you actually declare dependency to the 'default' configuration of the projectA. If you need to depend on a specific configuration of projectA, use map notation for projects:
configurationName project(path: ':projectA', configuration: 'someOtherConfiguration')
Project dependencies are represented using a ProjectDependency.
You can also add a dependency using a FileCollection:
configurationName files('a file')
apply plugin: 'java'
//so that we can use 'compile', 'testCompile' for dependencies
dependencies {
//declaring arbitrary files as dependencies
compile files('hibernate.jar', 'libs/spring.jar')
//putting all jars from 'libs' onto compile classpath
compile fileTree('libs')
}
File dependencies are represented using a SelfResolvingDependency.
You can add a dependency using a Configuration.
When the configuration is from the same project as the target configuration, the target configuration is changed to extend from the provided configuration.
When the configuration is from a different project, a project dependency is added.
It is possible to depend on certain Gradle APIs or libraries that Gradle ships with. It is particularly useful for Gradle plugin development. Example:
//Our Gradle plugin is written in groovy
apply plugin: 'groovy'
//now we can use the 'compile' configuration for declaring dependencies
dependencies {
//we will use the Groovy version that ships with Gradle:
compile localGroovy()
//our plugin requires Gradle API interfaces and classes to compile:
compile gradleApi()
}
To add a client module to a configuration you can use the notation:
configurationName module(moduleNotation) {
module dependencies
}
The module notation is the same as the dependency notations described above, except that the classifier property is
not available. Client modules are represented using a ClientModule.| 修飾子とタイプ | メソッドと説明 |
