Export to runnable jar is missing projects [message #1848369]

Hello,
I just using eclopse Version: 2021-09 (4.21.0) Build id: 20210910-1417
I want to export my project as a runnable jar. It is a JPA project.
My project uses also other projects and these are added in the Projects tab in the Build Path and checked (if necessary in the Order and Export tab also in the Build Path).
When I exported this project I got a classNotFoundException.
And after investigation I saw that when I opened the jar with 7Zip that the projects ar missing. I tried all the three options which you can choose during the export (Extract, Package , Copy) and all runnable jars give the same results.
In a earlier version of Eclipse f.i. 2020-09 it worked.
But lately my computer crashed and I had to reinstall everything and also eclipse. Maybe this had impact on the way Export works.

I found out that if I create a new JAVA Project the export works but as soon as I converted it to a MAVEN project it doesn't work anymore the other Projects from the build path are not in the jar anymore .

I hope someone can give me some tips to get it work again.
Thanks,
John

:It's a bit late for this user, but if anyone else has this problem, here's something to check.

In addition to adding the Project to the Java Build Path in the Project Properties, be sure to add the Project to the Classpath Entries under Dependencies in the Run Configuration you are using when exporting as a runnable jar.

Thank you very much for posting this!

This solved my problem!

(I don't know if this is a feature or a bug, but I **would** think that if I want to export a 'runnable Jar', well, then I want to export a runnable jar.)

My scenario: I develop in one environment (happens to be a local machine, with Eclipse) and I go live on AWS, on a small, headless machine. I installed there Java (yes, I know that in order to run a jar, I need Java) but I didn't install any of the referenced libraries. Why would I if Eclipse (on better days) can do it for me.
