Hi, I have some feedback about this page
I am getting error when compiling

Turns out, this is an issue with at least Maven 3.9.0 (3.9.2 installed locally). I downgraded Maven and now the custom jar is deployed successfully to Veridian. I got help from https://stackoverflow.com/questions/75652635/a-required-class-was-missing-while-executing-maven-plugin-with-github-action. I downgraded Maven to 3.6.3 and used Maven Wrapper to compile the code which fixed the issue (downgrading is easier as opposed to installing older Maven version manually)
mvn wrapper:wrapper -Dmaven=3.6.3
mvnw clean package hazelcast-cloud:deploy
Just highlighting this in as you might want to mention this in the page.
