	-Pfile="src/main/java/hello/world/Calculator.java" \
	-Pcut="hello.world.Calculator" \
	-Pcp="/home/ubuntu/research-work-2024/sample-projects/hello-world-java/build/classes:/home/ubuntu/research-work-2024/sample-projects/hello-world-java/build/classes/java:/home/ubuntu/research-work-2024/sample-projects/hello-world-java/build/classes/java/main" \

Other notes

The PR is not for merging! See below.

What is missing?

The modifications are messy; I do not plan to merge the PR into development. The PR is opened as a draft to raise awareness of other folks.

Perhaps, it is not needed.
