## IDEA 编译 ElasticSearch 7.8 ##

### 环境准备 ###

*  ElasticSearch 7.8.1
 *  jdk14
 *  gradle-6.5
 *  elasticsearch-7.8.1-windows-x86\_64 (与源码版本一致)
 *  IDEA 2019.3

#### JDK14 ####

1.  下载地址：https://www.oracle.com/java/technologies/javase-jdk14-downloads.html
2.  配置环境变量

可能存在的问题：  
从jdk 8 切换到 jdk 14时，环境变量配置完成之后，cmd 输入 java -version 显示仍然是1.8的版本

删除 C:\\ProgramData\\Oracle\\Java\\javapath下的jar即可。

#### gradle ####

1.  下载 gradle-6.5-all.zip
2.  配置环境变量
3.  修改C:\\Users\\Admin.gradle\\init.gradle

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://repo.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
            }
        }
    }

#### 下载es源码 ####

git clone：

git clone https://github.com/elastic/elasticsearch.git

切换版本

git checkout 7.8

可能存在的问题：  
如果发现git 到最后报错了，可能是由于文件过大引起的，可以按照报错去搜索解决办法。

#### 安装es ####

1.  下载地址 ：https://www.elastic.co/cn/downloads/past-releases/elasticsearch-7.8.1
2.  解压即可

### 编译 ###

7.8版本的es导入idea十分简单，不需要在执行类似 gredlew idea 这样的编译操作 ，直接 使用idea import 即可，具体可以查看 源码文件 elasticsearch\\CONTRIBUTING.md中关于idea导入部分的描述。

### 运行 ###

1.启动类 位于 ：elasticsearch\\server\\src\\main\\java\\org\\elasticsearch\\bootstrap\\Elasticsearch.java,运行会报错

ERROR: the system property [es.path.conf] must be set

在idea的run configuration，vm options中加入

-Des.path.conf=D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1\config

2.运行再次报错

Exception in thread "main" java.lang.IllegalStateException: path.home is not configured

在idea的run configuration，vm options中加入

-Des.path.home=D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1

3.再次运行报错 ：

Exception in thread "main" java.lang.NullPointerException
    	at org.elasticsearch.node.InternalSettingsPreparer.checkSettingsForTerminalDeprecation(InternalSettingsPreparer.java:119)
    	at org.elasticsearch.node.InternalSettingsPreparer.prepareEnvironment(InternalSettingsPreparer.java:91)

    	at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:126)
    	at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92)

修改 D:\\ProgramFiles\\ElasticSearch\\elasticsearch-7.8.1-windows-x86\_64\\elasticsearch-7.8.1\\config\\elasticsearch.yml 配置中的node.name

随便起个名称应该都可以

node.name: node-1

4.再次运行 ，报错：

    	at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92)

vm options中加入

-Dlog4j2.disable.jmx=true

5.再次运行报错：

    	at org.elasticsearch.bootstrap.Elasticsearch.main(Elasticsearch.java:92)

在config目录新建 java.policy，并填入：

grant {
    	permission java.lang.RuntimePermission "createClassLoader";
    };

在VM options中加入

-Djava.security.policy = D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1\config\java.policy

VM.options 最后的模样：

-Des.path.conf=D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1\config
    -Des.path.home=D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1
    -Dlog4j2.disable.jmx=true
    -Djava.security.policy=D:\ProgramFiles\ElasticSearch\elasticsearch-7.8.1-windows-x86_64\elasticsearch-7.8.1\config\java.policy

再次运行，成功
