Recently, I was working on a micro-service using Ratpack framework. \u00a0I wanted to deploy it to Heroku. I had tried to find good documentation for deploying on Heroku but couldn’t find as such.\u00a0After much trial and error, I finally managed to get a working configuration for successful deployment. As Heroku has very good support for Gradle-based projects and just we need to give right configuration details and all would be done. So, Here are the steps for right configuration:<\/p>\n
Artifacts:\u00a0<\/strong>we would need to create some files at root of the project which would contain<\/p>\n \u00a0 1. system.properties<\/span><\/em>: \u00a0It will let\u00a0Heroku \u00a0know which version of java to be used<\/p>\n \u00a0 2. settings.gradle<\/span><\/em>:<\/p>\n \u00a0 3. Procfile<\/span><\/em>: It would\u00a0let\u00a0Heroku know from where it needs to pick a big fat jar of the project and what command, it needs to execute to run project.<\/p>\n Edit build.gradle:\u00a0<\/strong>we would need to add a dependency \u00a0in buildscript for buildingfat jar<\/p>\n and closure of Task stage<\/em>\u00a0:<\/p>\n This above code will help in generating big fat jar of ratpack application with name project_name-all.jar when Heroku would run “gradle stage” task for building the code.<\/p>\n <\/p>\n Just That’s it… Recently, I was working on a micro-service using Ratpack framework. \u00a0I wanted to deploy it to Heroku.
