can anybody help how to deploy jar file to the heroku using pipeline script .

# This is a sample build configuration for Java (Maven).

image: maven:3.6.1
clone: 
  depth: full

pipelines: 
  branches: 
    master:
     - step: 
       name: Build and Deploy Snapshot Artifact 
       trigger: automatic
       image: maven:3 
       caches: - maven # cache the maven 
       script: 
          - mvn install clean 
          - mvn package 
  
     - step: name: Create artifact in HEROKU - Prod 
       deployment: production 
       script: 
          - git push https://heroku:$HEROKU_API_KEY@git.heroku.com/$HEROKU_APP_NAME.git HEAD:master

Hi @vinoth_ssv ,

Thank you for your question!

Let's use heroku-deploy pipe in your case.

Also, we have an example of how to deploy a Java app with the heroku-deploy pipe.

@vinoth_ssv  I have successfully used a pipeline to deploy to heroku using the heroku-maven-plugin 

First add the plugin to your pom

<plugin>
   <groupId>com.heroku.sdk</groupId>
   <artifactId>heroku-maven-plugin</artifactId>
   <version>3.0.2</version>
   <configuration>
      <appName>migal-resume</appName>
      <includeTarget>false</includeTarget>
      <includes>
         <include>${project.build.directory}/${project.build.finalName}.jar</include>
      </includes>
      <jdkVersion>1.8</jdkVersion>
      <processTypes>
         <web>java $JAVA_OPTS -jar target/${project.build.finalName}.jar -Dserver.port=$PORT</web>
      </processTypes>
   </configuration>
</plugin>

then  you will need to get your heroku api key and add it to your Deployment Variables in Btbucket

and then to deploy add - HEROKU_API_KEY=$HEROKU_API_KEY mvn heroku:deploy

       caches: - maven # cache the maven 
       script: 
         - mvn install clean 
         - mvn package 
 
     - step: name: Create artifact in HEROKU - Prod 
       deployment: production 
       script: 
         - HEROKU_API_KEY=$HEROKU_API_KEY mvn heroku:deploy

I hope this helps
