The project name is not required in the 5.0.0-m1 or 5.0.0-m2 releases. The documentation that is published is for the m2 release. You can see here that the project argument is no longer required:

DependencyCheck/cli/src/main/java/org/owasp/dependencycheck/CliParser.java

Lines 1021 to 1027 in 0a7cc78

	public String getProjectName() {
	String name = line.getOptionValue(ARGUMENT.PROJECT);
	if (name == null) {
	name = "";
	}
	return name;
	}

We hope to be code complete with the 5.0.0 branch soon. Sorry for the confusion.
