please do not put screenshots in here, and properly format your code snippets. This forums supports markdown, please make use of it. Thanks!

You have to specify a URL when installing a plugin. If the plugin is stored locally already, you can use file:// as a prefix. That said, running elasticsearch-plugin install analysis-icu should work out of the box, if you have an internet connection.

HI Alexander,
I passed the following commands to install the plugin:

  1. elasticsearch-plugin.bat install file:\\C:\Users\myuser\Documents\analysis-icu-7.3.1.zip

  2. elasticsearch-plugin.bat install file://C:\Users\myuser\Documents\analysis-icu-7.3.1.zip

  3. elasticsearch-plugin.bat install file://C:/Users/myuser/Documents/analysis-icu-7.3.1.zip

For all of the above commands, I got the following error:

Exception in thread "main" java.net.UnknownHostException: C at java.base/java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocke
tImpl.java:220)

See https://www.elastic.co/guide/en/elasticsearch/plugins/current/plugin-management-custom-url.html

This works, now I know I was passing the wrong path and using the file:/// in wrong manner

Unfortunately with the correct path, now I am getting an error from the plugin-descriptor.properties

I executed the following command:
elasticsearch-plugin.bat install file:///C:/mypath/analysis-icu-7.3.1.zip

It gave me the following error:
