Win 10 ElasticSearch源码本地调试

如何在本地调试ElasticSearch源码？

下载代码

此处以我平时学习的代码为例

git clone git@github.com:jiankunking/elasticsearch.git

导入到Idea

原文地址：https://github.com/jiankunking/elasticsearch/blob/master/CONTRIBUTING.md

Idea 代码运行

Debug Elasticsearch是idea导入代码后自动有的，但要注意下图红框1、2两处配置

https://discuss.elastic.co/t/failing-to-run-on-intellij-in-debug-mode/227805/3

本地代码运行

cd到代码根目录

执行如下命令

./gradlew run --debug-jvm

看到界面显示如下

表示代码已经启动完成

请求调用

这时候就可以在idea代码中添加断点了

curl --location 'http://localhost:9200' \
--header 'Authorization: Basic ZWxhc3RpYzpwYXNzd29yZA=='

返回
