I am trying to setup codepipeline in AWS for Java Gradle application. The application is building fine. But when the jar file to uploaded to Elastic Beanstalk, I get 502 bad gateway nginx error. When I pull the logs, this is what I see.

But when I compile locally on my laptop (Windows) and that jar when I upload manually to codepipeline, its working fine. Jar file created through codepipeline, is giving the error.

AWS codepipeline env: Amazon Linux, Ubuntu
Java 1.8
Gradle 4.4

I tried comparing jar file from codepipeline and from local, only difference is the file size. I tried using Amazon linux, Ubuntu and Windows image to build from codepipeline, but no luck. Also moved the jar file to base directory. Still the same error

post_build:
commands:
# move the jar (by wildcard, agnostic to its name) to top level app.jar
– mv build/libs/*.jar app.jar
artifacts:
files:
# publish the now top level app.jar as the artifact
– app.jar
