Hi all, I want to make a bit modification to http input plugin, so to start with this task, i following steps: 1. Install logstash 7.14 downloading logstash-7.14.0-darwin-x86\_64.tar.gz, and test if installation is ok ```auto bin/logstash -e 'input{stdin{}}' ``` 1. Clone the input plugin: ```auto git https://github.com/logstash-plugins/logstash-input-http.git ``` 1. Build input plugin without any modification. ```auto [gustavo@MacBookGus logstash-input-http (master)]$ gem build logstash-input-http.gemspec WARNING: license value 'Apache License (2.0)' is invalid.

Adding more info. I running logstash again, with debug level log enabled, ```auto bin/logstash --log.level debug -e 'input{http{}}' .. [2021-08-05T15:10:14,422][DEBUG][logstash.plugins.registry] Tried to load a plugin's code, but failed. {:exception=>#, :path=>"logstash-input-http_jars", :type=>"input", :name=>"http"} [2021-08-05T15:10:14,429][ERROR][logstash.plugins.registry] Unable to load plugin. {:type=>"input", :name=>"http"} ``` ---

Finally i found the problem. I missed build logstash-input-http plugin and i hadn't installed jruby in my system. these are the steps i followed to resolve this: 1. brew install jruby 2. Clone logstash project and build it. 3. On plugin project run ```auto jruby -S bundle install gradlew build gradlew vendor ``` 1. Install this local plugin in my logstash installed and after that the jars missing was generated and the filter was found. All work fine ! ---
