Spring Boot App on AWS Continious Deployment with GitHub

Question

I'm learning how work with AWS, and now I'm trying to do a codepipeline connecting AWS and GitHub (a spring boot jar applicacion). I have connected with GitHub and compile the sources but the deployment fails.

This is the error showed in the pipeline:

I have gone to the log that specify the error and find this other description:

2022/05/09 20:38:31.199534 [INFO] Job for web.service failed because the control process exited with error code. See "systemctl status web.service" and "journalctl -xe" for details.

2022/05/09 20:38:31.199559 [ERROR] An error occurred during execution of command [app-deploy] - [FlipApplication]. Stop running the command. Error: Register application failed because the registration of proc web failed: 
startProcess Failure: starting process "web" failed: Command /bin/sh -c systemctl start web.service failed with error exit status 1. Stderr:Job for web.service failed because the control process exited with error code. See "systemctl status web.service" and "journalctl -xe" for details.

But I don't understand. I looking in the web and try but it still not work. I have change the version from pom.xm already. This is the buildspec.yml that I use:

version: 0.2
 
phases:
  install:
    runtime-versions:
      java: corretto11
    commands:
      - echo install
  pre_build:
    commands:
      - echo pre_build
  build:
    commands:
      - mvn package
      - echo build
  post_build:
    commands:
      - echo post_build

artifacts:
  files:
    - '**/*'
    - target/02-todo-rest-api-h2-0.0.2-SNAPSHOT.jar

I add the codepipeline configuration's summary:

Thanks in advance for your help.
