This Java project is built with Apache Maven. Additionally, a Makefile is also provided for convenience. Before building this project, please ensure Maven is installed on the system. Optionally, GNU Make can be helpful to simplify the Maven and JRE commands.

To build the program, use Maven CLI:

$ mvn clean package

or

$ make

This will build the project to a jar file located in the target directory of the project root.

For simple execution without any command line arguments, run

$ java -cp target/elevator-sim-1.0-SNAPSHOT.jar io.yiyuzhou.app.App

or

$ make run

There are two command line arguments allowed:

• A path to the property file.
• A verbose flag for additional debug information.

For example, assuming you are on a standard GNU/Linux distribution. Your user name is foo, and there exists a property file called bar at location /home/foo/Documents/bar. You can run the program with that file path as one of the arguments:

$ java -cp target/elevator-sim-1.0-SNAPSHOT.jar io.yiyuzhou.app.App /home/foo/Documents/bar

Please note that the UNIX style "shortcut" ~, denoting the home directory will not work. This is due to a limitation of Java's File object implementation.

Likewise, the verbose flag would help you to debug by outputting some useful information to the shell.

$ java -cp target/elevator-sim-1.0-SNAPSHOT.jar io.yiyuzhou.app.App -v

or

$ make verbose
