If you are using Maven, see the Heroku Maven plugin, which is a more robust method of WAR and JAR file deployment.
You will require the following:
Run the following command to confirm:
$ java -version java version "1.7.0_51" Java(TM) SE Runtime Environment (build 1.7.0_51-b13) Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)
Use the following command to install the
$ heroku plugins:install heroku-cli-deploy
Use the following command to create a new application on Heroku
$ heroku create
You can use any method to generate a WAR file. You can use
ant or simply export your application from your IDE as a WAR file.
The only requirement is that the WAR file is a standard Java web application and adheres to the standard web application structure and conventions.
In order to deploy your WAR use the following command:
$ heroku war:deploy <path_to_war_file> --app <app_name> Uploading my-app.war.... ---> Packaging application... - app: my-app - including: webapp-runner.jar - including: my-app.war ---> Creating build... - file: slug.tgz - size: 1MB ---> Uploading build... - success ---> Deploying... remote: remote: -----> Fetching custom tar buildpack... done remote: -----> JVM Common app detected remote: -----> Installing OpenJDK 1.8... done remote: -----> Discovering process types remote: Procfile declares types -> web remote: remote: -----> Compressing... done, 50.3MB remote: -----> Launching... done, v5 remote: https://my-app.herokuapp.com/ deployed to Heroku remote: ---> Done
If you are in an application directory, you can use the following command instead:
heroku deploy:war <path_to_war_file>
Use the following command to open the application on the browser:
You can learn how to customize the deploy (such as including files and setting Tomcat options) in Configuring WAR Deployment with the Heroku Toolbelt.
You can also use this tool to deploy executable JAR files. To do so, run a command like this:
$ heroku deploy:jar <path_to_jar> --app <appname>
Available options include:
-j, --jar FILE # jar or war to deploy -v, --jdk VERSION # 7 or 8. defaults to 8 -o, --options OPTS # options passed to the jar file -i, --includes FILES # list of files to include in the slug
You can customize the command used to run your application by creating a
Procfile in the same directory as your run the
heroku deploy:jar command. For example:
web: java -cp my-uberjar.jar com.foo.MyMain opt1 opt2
You can view your current Procfile command by running
You can run your WAR file locally the way it is run on Heroku by executing this command:
$ heroku war:run <path_to_war>
To run the tests:
$ bash bin/test
To update the heroku-deploy-complete.jar:
$ bash update.sh <version>
For a list of versions see Maven Central.
To publish this plugin:
$ npm version <version> $ npm publish
