Elastic Beanstalk fails creating

I finally reached the point where my Elastic Beanstalk Instance / Environment got launched. (Java Corretto 11 Platform) Now it fails starting up the provided .jar file.
In the eb-engine.log file, I am not able to find any more error than this:
2021/05/27 11:36:25.889735 [INFO] Executing instruction: StageJavaApplication
2021/05/27 11:36:25.889871 [ERROR] An error occurred during execution of command [app-deploy] - [StageJavaApplication]. Stop running the command. Error: staging java app failed due to invalid zip file
The jar file is a Spring Boot application built with mvn -B package.
Locally the whole thing starts, but crashes afterwards because of not given environment variables (Expected behaviour).
But it seems AWS is not even starting the application..
Any suggestions on this?

Spring Boot apps run nicely on Elastic Beanstalk. However, you do need to set some variables. For example, have you set server-port variable to 5000?
And as you stated, to successfully use a Service Client, you can set environment variables for your creds. Here is an end to end walkthrough that shows how to successfully put a Spring BOOT app that invokes several AWS Services on Elastic Beanstalk.
Creating your first AWS Java web application
PS - your log file mentions a ZIP file. Be sure to create the JAR properly as discussed in the above example.

Just in case someone arrive here looking for an answer about this guy:
Error: staging java app failed due to invalid zip file
I was renaming my service jar in Gradle, using:
tasks.withType<org.springframework.boot.gradle.tasks.bundling.BootJar> {
archiveFileName.set("service.jar")
launchScript()
}
And ElasticBeanstalk was not happy about the renaming.
When I let it have the default name, then no zip issues and all worked like a charm.

istio error: Details: java.io.IOException: Unknown apiVersionKind

I receive this error message in jenkins when trying to deploy my application to kubernetes. Is there something I am missing?
istio-gateway.yml ERROR: ERROR: java.io.IOException: ERROR: YAML file
istio-gateway.yml is invalid, please check it. Details:
java.io.IOException: Unknown apiVersionKind:

I am using Spring Boot with Java

You are trying to create a Istio Geteway using that yaml. You probably don't have istio installed in your Kubernetes cluster. If it's not installed then you need to install it.

JAR creation failed using Upload Function to AWS Lambda in Eclipse

While using the AWS Toolkit for Eclipse, an error has been encountered when attempting to upload a Lambda function; the error is that that JAR creation failed. It is a simple "Hello World" application that was created to ensure that the environment is working; it follows the AWS tutorial: https://docs.amazonaws.cn/toolkit-for-eclipse/v1/user-guide/lambda-tutorial.html
The "Maven Build..." works fine to create the JAR without any error; following the steps in https://docs.amazonaws.cn/en_us/lambda/latest/dg/java-create-jar-pkg-maven-and-eclipse.html.
Eclipse is being run on a Mac and the JRE is Amazon Corretto 11 (11.0.4).
Any suggestions?
Here are the details of the errors:

Deploying Java web application on Openshift3

Azure specific reading files from local on spark

I am struggling with Azure wasb on spark
I am reading loading a .json.gz file from disk and loading it into hdfs. I have used the following code extensively on other systems.
val file_a_raw = sqlContext.read.json('/home/users/repo_test/file_a.json.gz')
However, on Azure, this returns:
java.io.FileNotFoundException: Filewasb://server-2017-03-07t08-13-41-314z#server.blob.core.windows.net/home/users/repo_test/file_a.json.gz does not exist.
I have checked this location and the file is there and correct.
I think there should be a : between .net and then file path, but I get a java error trying to manually add that in.
java.lang.IllegalArgumentException: java.net.URISyntaxException: Expected scheme name at index 0:
I've also tried:
Filewasb:///home/users/repo_test/file_a.json.gz
But that returns:
java.io.IOException: No FileSystem for scheme: Filewasb
This code works fine on non Azure spark

For Azure, you'll need to configure Spark with the proper credentials. Databricks has documentation on this: https://docs.databricks.com/user-guide/faq/azure-blob-storage.html
