Hi All,
I am trying to write a java filter plugin - following the instructions at - [https://www.elastic.co/guide/en/logstash/current/java-filter-plugin.html](https://www.elastic.co/guide/en/logstash/current/java-filter-plugin.html)
I am able to compile and install it locally and able to create an offline pack as well using below command :
```
bin/logstash-plugin prepare-offline-pack logstash-filter-java_filter_example
```
When I try to install this zip file using below command it fails
```
bin/logstash-plugin install file:///home/buch/logstash-offline-plugins-7.3.2.zip
```
-- (a few warnings)---
Installing file: /home/buch/logstash-offline-plugins-7.3.2.zip
ERROR: Something went wrong when installing file:///home/buch/logstash-offline-plugins-7.3.2.zip, message: Illformed requirement ["=java\_filter\_example"]
How do I get this fixed?
