at /Users/madhav.kelkar/.rvm/gems/jruby-9.1.6.0/bin/jruby_executable_hooks:15 ``` Here is my gemspec - ``` # Special flag to let us know this is actually a logstash plugin s.metadata = { "logstash_plugin" => "true", "logstash_group" => "input" } # Gem dependencies s.add_runtime_dependency "logstash-core-plugin-api", ">= 1.60", "<= 2.99" s.add_runtime_dependency 'logstash-codec-plain', "3.0.2" s.add_runtime_dependency 'stud', '0.0.22' s.add_development_dependency 'logstash-devutils', '1.1.0' ``` l did some research, and looks like there was indeed a problem - [https://github.com/elastic/logstash/issues/6374](https://github.com/elastic/logstash/issues/6374) Looks like latest available logstash-core-plugin-api (2.1.22) is using logstash-core 5.1.1.1. My theory is that if a version of logstash-core-plugin-api becomes available which uses logstash-core 5.1.2/5.2.0, my error should go way if I use that version. Can someone confirm this? is there a workaround for errors that I am getting? Thanks, Madhav. ---

I have a website and I want to change the appearance, but the java code is creating an issue and it is giving errors. Can anyone help me in fixing this issue? I am not an expert of coding for the development of a website, due to which I am facing this issue and the person who helps me to write an essay for [Paper Writing Service](http://www.Aoneessays.net/) knows a little bit of coding; so he tried to help me. But the issue is not solved, so I need help for it. ---

Changing this line in gemspec worked for me.. ``` -s.add_development_dependency "logstash-devutils", +s.add_development_dependency "logstash-devutils", "~> 1.3", ">= 1.3.1" ``` ---

I got a similar mistake when attempting to introduce blog stash-yield email on logstash 5.1.1: A blunder happened while introducing logstash-center occasion java, and Bundler can't proceed. Ensure that [dissertation editing online](http://www.dissertationtime.co.uk/editing-service) succeeds before bundling. ---
