To install a plugin using JRuby, you first need to have JRuby installed on your system. Once you have JRuby installed, you can use the gem command to install plugins.
To install a plugin, you typically use the following command: gem install plugin_name. This command will download and install the specified plugin onto your system.
You can also specify the version of the plugin you want to install by including the version number after the plugin name, for example gem install plugin_name -v 1.0.0.
After the plugin is installed, you may need to require it in your code using require 'plugin_name' to use its functionality.
Overall, installing a plugin using JRuby is straightforward and similar to installing plugins with regular Ruby.

What is the risk involved in installing unknown plugins in jruby?
Installing unknown plugins in JRuby can pose several risks, including:
- Security vulnerabilities: Unknown plugins may contain malicious code that can compromise the security of the JRuby environment, leading to data breaches or other security incidents.
- Performance issues: Poorly-written or incompatible plugins can cause JRuby to slow down or crash, affecting the performance and stability of the application.
- Compatibility issues: Unknown plugins may not be compatible with the other components of the JRuby environment, leading to errors or inconsistencies in behavior.
- Lack of support: Since unknown plugins may not be well-documented or supported by the developer community, it can be difficult to troubleshoot or resolve issues that arise from using them.
- Dependencies: Plugins may introduce additional dependencies that need to be managed and updated, increasing the complexity of the JRuby environment and potentially creating conflicts with existing components.
