Likely root cause: java.nio.file.NoSuchFileException: /usr/local/es/plugins/ik/plugin-descriptor（踩坑）

1. 安装ik分词器（本人下载的是第三个.tar.gz的源码包）

下载地址：https://github.com/medcl/elasticsearch-analysis-ik/

2. 安装报错

下载对应版本的ik分词器（java项目），将ik分词器放在es/plugins目录下，重启es导致报错

3. 解决方案

查阅官方文档内容可以知道

git clone https://github.com/medcl/elasticsearch-analysis-ik

cd elasticsearch-analysis-ik

git checkout tags/{version}

mvn clean

mvn compile

mvn package

拷贝和解压release下的文件: #{project_path}/elasticsearch-analysis-ik/target/releases/elasticsearch-analysis-ik-*.zip 到你的 elasticsearch 插件目录, 如: plugins/ik 重启elasticsearch

所以需要我们把项目克隆到idea里面，然后用上面三个命令打包，然后在target/releases/目录下找到.zip文件；

4. windows系统直接解压缩就好了，macos可以用The Uncharvier解压缩，很方便！最后可以利用一个很高效的linux连接工具，把文件传输自定义的es目录下的plugins目录下即可！最后重启,后面又报下面的错误

5. 报错信息： failed to load plugins analysis-ik due to jar hell
