Latest jar is not running in Auto code deploy

Question

This a Java based application. Deploying the application by using Code Deploy. By using Bitbucket pipeline, the latest jar file is uploaded to S3 bucket. The latest .jar is getting replaced with updated jar after pipeline triggered or Auto scaling timings. But the process is not running with latest jar. we are killing the existing processes and starting them manually to run the latest jar.

Could you please guide us on how to resolve the issue to run the jar automatically without triggering manually
appspec.yml:
--------------------------
hooks:
   AfterInstall:
    - location: deploymentscripts/serviceApp.bash
      runas: root
  ApplicationStart:
    - location: deploymentscripts/startApp.bash
      runas: root

serviceApp.bash
--------------------------------
#Copy jar file to /usr/local/app_name
sudo mkdir /usr/local/app_name
sudo cp -f /usr/local/app_name/target/app_name-0.0.1-SNAPSHOT.jar /usr/local/app_name/app_name-0.0.1-SNAPSHOT.jar
#Create service file
sudo touch /etc/systemd/system/app_name.service
sudo > /etc/systemd/system/app_name.service
#add exucute permission to service file
sudo chmod 664 /etc/systemd/system/app_name.service
sudo chmod +x /usr/local/app_name/app_name-0.0.1-SNAPSHOT.jar

startApp.bash
-----------------
sudo java -Dspring.profiles.active=env_name -Dlog_path=/usr/local/app_name -jar /usr/local/app_name/app_name-0.0.1-SNAPSHOT.jar &>/dev/null &

Answer

Greetings,
From the case notes, I understand that you need guidance on how to run the .jar automatically without triggering manually appspec.yml
CodeDeploy will use the appspec.yml file in the source code therefore issuing instruction on how to deploy the application. 
Once the application has been packaged the appspec file is no longer in use[1]

You can include the same script 'serviceApp.bash' and  'startApp.bash' on the appspec file following the guideline[1] to trigger the desired configurations.
