HelloWorld example

[rpx99]

First of all thanks a lot for this great project and the great work you put into it!

I looked into the Getting Started section of the documentation and followed the link at the end of the page:

The full code for the Hello World example is on GitHub.

In my opinion - for a hello world - it is too complicated to execute the example and simply get started. I cannot find instructions how to actually run only the hello world example. How is it meant to run ?

Here is what I did:

tron$ pwd
/home/rpx/Downloads
tron$ git clone https://github.com/eclipse-store/store.git
tron$ cd store/examples/helloworld

Extended the pom.xml file like so:

`

tron$ mvn clean install

Ran the program:

tron$ java -jar target/examples-helloworld-1.2.0-SNAPSHOT-jar-with-dependencies.jar

Thank you.

Hi,
Most of the examples are just small main methods demonstrating basic usages of eclipse store.
They are no real applications; they are best run in an IDE of your choice.
The only exception is the spring-boot3-simple example. Please see the related readme.
