6.1.2版本elasticsearch源码环境构建步骤(idea)

ElasticSearch构建源码环境步骤：

以版本6.1.2 on mac, idea为例

准备：gradle 4.3版本。jdk10。

jdk10 mac版本可以到我的百度云获取：

修改~/.gradle/init.gradle文件：

allprojects{
    repositories {
        def ALIYUN_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
        def ALIYUN_JCENTER_URL = 'http://maven.aliyun.com/nexus/content/repositories/jcenter'
        def GRADLE_LOCAL_RELEASE_URL = 'https://repo.gradle.org/gradle/libs-releases-local'
        def ALIYUN_SPRING_RELEASE_URL = 'https://maven.aliyun.com/repository/spring-plugin'
        
        all { ArtifactRepository repo ->
            if(repo instanceof MavenArtifactRepository){
                def url = repo.url.toString()
                if (url.startsWith('https://repo1.maven.org/maven2')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_REPOSITORY_URL."
                    remove repo
                }
                if (url.startsWith('https://jcenter.bintray.com/')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_JCENTER_URL."
                    remove repo
                }
                if (url.startsWith('http://repo.spring.io/plugins-release')) {
                    project.logger.lifecycle "Repository ${repo.url} replaced by $ALIYUN_SPRING_RELEASE_URL."
                    remove repo
                }
                
            }
        }
        maven {
            url ALIYUN_REPOSITORY_URL     
        }
        
        maven {            
            url ALIYUN_JCENTER_URL          
        }
        maven {            
            url ALIYUN_SPRING_RELEASE_URL
        }
        maven {
            url GRADLE_LOCAL_RELEASE_URL
        }
        
    }
}

1. 修改配置

下载git源码后，终端下cd 到es目录下

执行./gradlew idea

会遇到以下问题

（1）下载地址解析问题，如distribution模块，那么到这个模块下，修改build.gradle，加入以下内容：

buildscript {
  repositories {
    maven {url "https://plugins.gradle.org/m2/"}
    maven {url 'http://maven.aliyun.com/nexus/content/groups/public/' }
    maven {url 'http://repo.maven.apache.org/maven2' }

  }
  dependencies {
    classpath 'com.netflix.nebula:gradle-ospackage-plugin:3.4.0'
  }
}

如benchmarks模块：

buildscript {
    repositories {
        maven {url 'https://plugins.gradle.org/m2/' }
        maven {url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven {url 'http://repo.maven.apache.org/maven2' }
    }
    dependencies {
        classpath 'com.github.jengelman.gradle.plugins:shadow:1.2.4'
    }
}

（2）java_home问题：

将该groovy文件（buildSrc/src/main/groovy/org/elasticsearch/gradle/BuildPlugin.groovy）

中：

String javaHome = System.getenv('JAVA_HOME')

改为绝对地址路径

String javaHome = "/Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/Contents/Home"

解决以上问题后再次执行，直到出现则编译成功，如果只需要编译，则到此就可以了。

BUILD SUCCESSFUL in 15s

2. idea环境

idea下编译需要修改gradle配置：

1. 选择Use Gradle 'wrapper' task configuration
2. JVM配置jdk1.8（idea不兼容问题）
3. Service directory path选择：～/.gradle

刷新import，开始build
