It's been a long time since I did some serious coding. The last one I did was to do some manipulation within AWS S3 buckets. It was some 4 or 5 years ago.
Time is one major reason I couldn't keep myself up-to-date. Whenever I try to scan the new trends I could feel that how old I have become.
Even Java which is my foundation now seems like a totally distant language. There have been so many changes.
I am from ant world and the maven world is kind of scary.
Just to refresh my rusty brain I wanted to try something out in AWS and lambda seemed to be harmless. I wanted to try Hello World in Lambda. I didn't realize what I was getting into.
The first step was to download latest java and Oracle said it is Java 15. I downloaded Java 15 and latest Eclipse 2021-03. I noticed Eclipse stopped naming their releases, guess they ran out of names.
Followed the steps in AWS tutorial and encountered "Unable to export Project to Jar file" error. When I searched on this I found that Java 15 is not the right version and Lambda recently support Java 11. But most articles said Lambda functions works only with Java 8.
Now latest eclipse doesn't work with Java 8. I was confused whether to go with 8 or 11. Tried my luck with 11 by downloading Java 11 and Eclipse which works with 11.
It didn't work I installed JRE 8 and used Eclipse version which worked with 11. I changed configuration to use JRE 8 but Eclipse was still using Java 11 and now I encountered "NoClassDefFoundError JAXBException".
Upon further checking it seems JAXB is not part of standard Java post version 10. So I had to go for an Eclipse which worked with Java 8. I downloaded Eclipse 2019-03 and then everything worked as expected.
Took me almost 2 days to get to this point.

You should try Intellij. You'll never go back to Eclipse.
