下载直接运行exe文件

下载es官网platinum版本

docker pull docker.elastic.co/elasticsearch/elasticsearch-platinum:6.2.3

运行

[root@localhost ES623]# docker run -itd --name test docker.elastic.co/elasticsearch/elasticsearch-platinum:6.2.3 bash
8ab342a0db2c8d5fe8bcaef9ca0f50e520ef2425c9f4730615d716a1d2a4c2e3
[root@localhost ES623]# 

拷贝jar

docker cp test:/usr/share/elasticsearch/plugins/x-pack/x-pack-core/x-pack-core-6.2.3.jar .

下载x-pack-core-6.2.3.jar到本地

反编译

打开后找到两个class文件，分别为org.elasticsearch.license.LicenseVerifier ,org.elasticsearch.xpack.core.XPackBuild

将反编译后的java 代码复制到自己的IDE中，按照同样的包名创建pack

我们不需要编译整个项目，只需要编译这两个文件，所以要把依赖添加到classpath中，

依赖也与之前有所变化，之前只需要x-pack 包本身，现在需要引入 elasticsearch 6.2.3 中 lib 目录下的jar包 以及 x-pack-core-6.2.3.jar 本身
