Usage

• The JinJava maven plugin can be used to template out any type of text files (eg .yml files,.txt. .json ...) during build. This plugin can be used when we need to generate text files based on the different context. (can be used when we need to generate yml based on host)

ansible

To execute the ansible ping module with the host as localhost
