插件可以像 Gradle 构建脚本或 Gradle 设置文件一样应用于 init 脚本。
在 init 脚本中使用插件
init.gradle.kts
apply
class EnterpriseRepositoryPlugin : Plugin
companion object {
const val ENTERPRISE_REPOSITORY_URL = "https://repo.gradle.org/gradle/repo"
}
override fun apply(gradle: Gradle) {
// ONLY USE ENTERPRISE REPO FOR DEPENDENCIES
gradle.allprojects {
repositories {
// Remove all repositories not pointing to the enterprise repository url
all {
if (this !is MavenArtifactRepository || url.toString() != ENTERPRISE_REPOSITORY_URL) {
project.logger.lifecycle("Repository ${(this as? MavenArtifactRepository)?.url ?: name} removed. Only $ENTERPRISE_REPOSITORY_URL is allowed")
remove(this)
}
}
// add the enterprise repository
add(maven {
name = "STANDARD_ENTERPRISE_REPO"
url = uri(ENTERPRISE_REPOSITORY_URL)
})
}
}
}
}
build.gradle.kts
repositories{
mavenCentral()
}
data class RepositoryData(val name: String, val url: URI)
tasks.register("showRepositories") {
val repositoryData = repositories.withType
doLast {
repositoryData.forEach {
println("repository: ${it.name} ('${it.url}')")
}
}
}
init.gradle
apply plugin: EnterpriseRepositoryPlugin
class EnterpriseRepositoryPlugin implements Plugin
private static String ENTERPRISE_REPOSITORY_URL = "https://repo.gradle.org/gradle/repo"
void apply(Gradle gradle) {
// ONLY USE ENTERPRISE REPO FOR DEPENDENCIES
gradle.allprojects { project ->
project.repositories {
// Remove all repositories not pointing to the enterprise repository url
all { ArtifactRepository repo ->
if (!(repo instanceof MavenArtifactRepository) ||
repo.url.toString() != ENTERPRISE_REPOSITORY_URL) {
project.logger.lifecycle "Repository ${repo.url} removed. Only $ENTERPRISE_REPOSITORY_URL is allowed"
remove repo
}
}
// add the enterprise repository
maven {
name = "STANDARD_ENTERPRISE_REPO"
url = ENTERPRISE_REPOSITORY_URL
}
}
}
}
}
build.gradle
repositories{
mavenCentral()
}
@Immutable
class RepositoryData {
String name
URI url
}
tasks.register('showRepositories') {
def repositoryData = repositories.collect { new RepositoryData(it.name, it.url) }
doLast {
repositoryData.each {
println "repository: ${it.name} ('${it.url}')"
}
}
}
> gradle --init-script init.gradle.kts -q showRepositories
repository: STANDARD_ENTERPRISE_REPO ('https://repo.gradle.org/gradle/repo')
> gradle --init-script init.gradle -q showRepositories
repository: STANDARD_ENTERPRISE_REPO ('https://repo.gradle.org/gradle/repo')
init 脚本中的插件确保在运行构建时只使用指定的仓库。
在 init 脚本中应用插件时，Gradle 会实例化插件并调用插件实例的 Plugin.apply(T) 方法。
gradle 对象作为参数传递，可用于配置构建的所有方面。当然，应用插件可以作为外部依赖项解析，如init 脚本的外部依赖项中所述
