gradle使用国内源加速构建

gradle

直接移除jcenter和mavenCentral,增加指定的maven

• 在项目的build.gradle配置,只对当前项目有效

allprojects{
    repositories {
        def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }
    }
}

• 在~/.gradle/下新建一个文件init.gradle用来全局初始化配置的脚本

allprojects{
    repositories {
        def REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2') || url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $REPOSITORY_URL."
                    remove repo
                }
            }
        }
        maven {
            url REPOSITORY_URL
        }
    }
}

不移除默认的jcenter和mavenCentral,在前面增加指定的maven

i.e.

allprojects{
    // 这里指定的是buildscript的repo
    buildscript{
        repositories{
            maven{
         url 'http://maven.aliyun.com/nexus/content/repositories/'       url 
            }
        }
    }
    // 这里指定的是project的repo
    repositories {
        println '优先使用aliyun maven'
        maven {
            url 'http://maven.aliyun.com/nexus/content/repositories/'
        }
    }
}

把这段script放到当前项目的build.gradle或者全局的init.gradle中
直接移除默认源有时候不够好，有时候我们指定的源可能网络问题访问不了，这时候就需要通过默认的源来访问。
在不改变各个原项目配置的情况下，建议使用全局配置初始化脚本的方式来做比较好。

附上init.gradle

def gradle = getGradle()
println "***************************************************"
println "Dump gradle information"
println "Version:${gradle.getGradleVersion()}"
println "UserHomeDir:${gradle.getGradleUserHomeDir()}"
println "HomeDir:${gradle.getGradleHomeDir()}"
println "***************************************************"
// Jinfuzi Maven credentials
def NEXUS_SERVER = "http://nexus.jfz.com/content/groups/public"
def NEXUS_USERNAME = "developer"
def NEXUS_PASSWORD = "jinfuzi2014"
// 阿里云 maven 服务器
def MAVEN_ALIYUN = 'http://maven.aliyun.com/nexus/content/groups/public'
allprojects {
    buildscript {
        repositories {
            maven {
                credentials {
                    username NEXUS_USERNAME
                    password NEXUS_PASSWORD
                }
                url NEXUS_SERVER
            }
            maven {
                url MAVEN_ALIYUN
            }
            jcenter()
        }
    }
    repositories {
        maven {
            credentials {
                username NEXUS_USERNAME
                password NEXUS_PASSWORD
            }
            url NEXUS_SERVER
        }
        maven {
            url MAVEN_ALIYUN
        }
        jcenter()
    }
}
