Here is a maven archetype to initialize a lightweight Jakarta EE and Eclipse MicroProfile Maven Project.
The Maven archetype is deployed in Maven-Central. Source code can be found in the Git-repository at https://github.com/bitofcode/archetype-jakartaee-microprofile.

mvn archetype:generate -DarchetypeGroupId=com.bitofcode.archetype -DarchetypeArtifactId=jakartaee-microprofile -DarchetypeVersion=0.0.2

I have created an alias like this: newJeeProject='mvn archetype:generate -DarchetypeGroupId=com.bitofcode.archetype -DarchetypeArtifactId=jakartaee-microprofile -DarchetypeVersion=0.0.2 -DarchetypeCatalog=local -DinteractiveMode=true'

The command above generate a maven multi-module project containing the app and the system-tests

$ newJeeProject
