一、软件环境
- 操作系统
Windows10
- 软件开发IDE
IDEA 2020.3.2
- Elasticsearch
{ "name" : "", "cluster_name" : "elasticsearch", "cluster_uuid" : "g3XhWHTmR-KelMCIPcq9Rw", "version" : { "number" : "7.12.1", "build_flavor" : "unknown", "build_type" : "unknown", "build_hash" : "unknown", "build_date" : "unknown", "build_snapshot" : true, "lucene_version" : "8.8.0", "minimum_wire_compatibility_version" : "6.8.0", "minimum_index_compatibility_version" : "6.0.0-beta1" }, "tagline" : "You Know, for Search" }
- JDK
java version "15.0.2" 2021-01-19 Java(TM) SE Runtime Environment (build 15.0.2+7-27) Java HotSpot(TM) 64-Bit Server VM (build 15.0.2+7-27, mixed mode, sharing)
这是另外下载的JDK，因为在构建过程中发现JDK8和JDK11都会报错。
这是我的笔记本里下载JDK环境，三者都有。
其中环境变量中的PATH里添加了JDK8的bin目录，如下图所示。
- 项目构建工具Gradle
从Elasticsearch5.0开始，构建工具由Maven改为Gradle。
------------------------------------------------------------ Gradle 7.0 ------------------------------------------------------------ Build time: 2021-04-09 22:27:31 UTC Revision: d5661e3f0e07a8caff705f1badf79fb5df8022c4 Kotlin: 1.4.31 Groovy: 3.0.7 Ant: Apache Ant(TM) version 1.10.9 compiled on September 27 2020 JVM: 1.8.0_201 (Oracle Corporation 25.201-b09) OS: Windows 10 10.0 amd64
操作系统的环境变量设置JDK版本为1.8，因此这里显示的JVM版本是1.8，但是在后面的构建过程中，在IDEA中会进行配置选择ES项目自定义的JDK，如上为1.15。
1.Gradle配置的详细信息为：
2.设置Gradle的国内源：
在gradle安装目录下的init.d文件夹中添加init.gradle文件。
init.gradle文件中添加如下代码：
allprojects{ repositories { def ALIYUN_REPOSITORY_URL = 'https://maven.aliyun.com/nexus/content/groups/public' def ALIYUN_JCENTER_URL = 'https://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 } } }
二、构建成功后的输出
======================================= Elasticsearch Build Hamster says Hello! Gradle Version : 7.0 OS Info : Windows 10 10.0 (amd64) JDK Version : 15 (Oracle) JAVA_HOME : D:\jdk-15.0.2 Random Testing Seed : 5882B1EC97E88DA1 In FIPS 140 mode : false ======================================= BUILD SUCCESSFUL in 1m 27s BUILD SUCCESSFUL in 2s
可以看到此时的JDK版本为1.15。
三、导入ES项目代码
Git方式下载到本地或者直接下载压缩包然后解压到本地即可。源代码文件目录如下图所示。
使用IDEA直接打开项目的根目录即可。
四、构建项目
构建完成后的项目目录如下图所示。
所有的包依赖也下载了Gradle安装目录中的caches文件夹中，如下图所示。
五、跑源码详细步骤
1. 跑源码前的准备
在源码根目录下新建文件夹eshome，将发行版中的config和modules文件夹复制过来。
2. 找到程序主文件Elasticsearch
文件路径为：
elasticsearch-7.12.1\server\src\main\java\org\elasticsearch\bootstrap\Elasticsearch.java
3. 点击运行按钮
这一步会报错
4. 编辑运行参数
点击工具栏中执行文本框中的下拉菜单，点击Edit Configurations...按钮。
弹出的运行配置界面如下图所示。
5. 修改运行参数
点击配置界面右上角的修改参数下拉菜单按钮。选择Add VM options。
在新增的虚拟机参数输入框中新增下述代码。
-Des.path.home=F:\respository\elasticsearch-7.12.1\eshome -Des.path.conf=F:\respository\elasticsearch-7.12.1\eshome\config -Xms1g -Xmx1g -Dlog4j2.disable.jmx=true -Djava.security.policy=F:\respository\elasticsearch-7.12.1\eshome\config\elasticsearch.policy
6. 根据提示修改安全文件
将提示的三处地方进行注释接即可。
7. 运行
修改好参数后，点击Apply按钮，接着点击运行按钮。运行成功后的控制台输出如图所示。
输出的详细日志为
