Troubleshooting Installation of PureEdgeSim: ClassNotFoundException

[khadija-djarraya]

I tried the following on an intel MacOS and a Windows.

• JDK Version: 20
• Apache Maven Version: 3.9.6

I installed git and maven, and followed the CLI steps to install PureEdgeSim.

git clone https://github.com/CharafeddineMechalikh/PureEdgeSim.git -> Done
cd PureEdgeSim (directory of the project)
mvn clean install -> BUILD SUCCESS
mvn exec:java -Dexec.mainClass="examples.Example1" -> BUILD FAILURE

This is the complete message received:

Please let me know if I am doing something wrong throughout this installation. I have also tried to install PureEdgeSim on IntelliJ and Eclipse using the steps provided in the README file, but I am still facing the same errors and I'm unable to resolve the issue.
