Kafka源码阅读环境搭建

下载Kafka源码

官方下载源码地址：http://archive.apache.org/dist/kafka/1.0.2/kafka-1.0.2-src.tgz

安装配置Gradle

官方gradle-4.8.1下载地址：https://services.gradle.org/distributions/gradle-4.8.1-bin.zip

解压gradle-4.8.1-bin.zip到⼀个⽬录，如下图：

配置环境变量，其中GRADLE_HOME指向gradle解压到的根⽬录，GRADLE_USER_HOME指向gradle的本地仓库位置。

进⼊GRADLE_USER_HOME⽬录，添加init.gradle，配置gradle的源

init.gradle内容：

allprojects {
    repositories {
        maven { url 'https://maven.aliyun.com/repository/public/' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}

        all { ArtifactRepository repo ->
            if (repo instanceof MavenArtifactRepository) {
                def url = repo.url.toString()

                if (url.startsWith('https://repo.maven.apache.org/maven2/') || url.startsWith('https://repo.maven.org/maven2') || 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
                }
            }
        }
    }

    buildscript {

        repositories {

            maven { url 'https://maven.aliyun.com/repository/public/'}
            maven { url 'https://maven.aliyun.com/nexus/content/repositories/google' }
            maven { url 'https://maven.aliyun.com/nexus/content/groups/public/' }
            maven { url 'https://maven.aliyun.com/nexus/content/repositories/jcenter'}
            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
                    }
                }
            }
        }
    }
