Project structure

• src/main/java - contains the source code
• src/test/java - contains tests

Run the project

Make sure you have got Java >= 18 and maven installed on your machine.
First you need to clean and build the project, run the command:

mvn clean install

This will run tests and generate a jar file with all the dependencies. Jar file will be located in target folder. For running the jar, run the command from project root for example with the following arguments:

java -jar target/cron-1.0-SNAPSHOT-jar-with-dependencies.jar "1,5-9 5 1/15 * * /usr/bin/command"

Alternatively, you can run the main method in App.java in your chosen IDE, e.g. IntelliJ Project is using lombock library, so you might need to install the plugin for your IDE and enable annotation processing.
