准备

本文以Elasticsearch 6.6 为例，介绍使用IDEA调试Elasticsearch源码的方法。

使用到的工具和版本如下：

组件	版本
jdk	corretto-11.0.16
gradle	5.6.4
groovy	4.0.4
IntelliJ IDEA	2022.1

IDEA选择

对比：分别试过IntelliJ IDEA 2018.2.4和Visual Studio Code遇到一些障碍最后还是在IntelliJ IDEA 2022.1顺利通过。IntelliJ IDEA 2018.2.4直接崩溃闪退。vscode有两个问题，代码debug和groovy暂时放弃。

辅助：能自动下载jdk，帮助选择openjdk版本和提供下载地址。

jdk选择和下载

jdk版本参考

gradle和jdk兼容性矩阵

兼容性矩阵

Java version	First Gradle version to support it
8	2.0
9	4.3
10	4.7
11	5.0
12	5.4
13	6.0
14	6.3
15	6.7
16	7.0
17	7.3
18	7.5

gradle下载和安装

用户主目录不用设置在系统盘下

distributionBase=GRADLE_USER_HOME

全局变量：GRADLE_USER_HOME设置成非系统盘

groovy选择

Gradle is tested with Groovy 1.5.8 through 4.0.0.Gradle plugins written in Groovy must use Groovy 3.x for compatibility with Gradle and Groovy DSL build scripts.

下载Elasticsearch源码

代码地址：https://github.com/elastic/elasticsearch.git

选择分支：6.6

编译

运行

验证

遇到问题和解决

jdk版本问题

Unable to start the daemon process.
This problem might be caused by incorrect configuration of the daemon.
For example, an unrecognized jvm option is used.
Please refer to the User Manual chapter on the daemon at

gradle版本问题

Cause: startup failed:

groovy版本问题

I am getting this exception?java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.vmplugin.v7.Java7  and java.lang.NoClassDefFoundError: Could not initialize class org.codehaus.groovy.reflection.ReflectionCache) when i run the spring

配置国内云仓库

 //  settings.gradle
buildscript {
  repositories {
    //对应google()
    maven {url 'https://maven.***.com/repository/google'}
    //对应jcenter()
    maven {url 'https://maven.***.com/repository/jcenter'}
    //公共库
    maven {url 'https://maven.***.com/repository/public'}

  }
}

gradle三方包占用系统盘问题
