Specifying batch mode program classpath and required system properties

MagicDraw or other modeling tool run as a simple Java program.

In order to launch the program from command line, the launcher is started using a java command line. The classpath has to include jar files from the lib folder and its subfolders (additional requirements exist for different command line implementations).

There is one mandatory property that has to be specified as well:

-Desi.system.config=data/application.conf

The property is specified as relative path to <modeling tool installation directory> therefore you either have to make your current directory before launching your program or to specify absolute paths for above listed properties.

There are two types of command lines.

Core related batch program:
A program that does not call/depend on any functionality from any plugins. Should only depend/call core tool functionality.
- Must extend com.nomagic.magicdraw.commandline.CommandLine
- Must contain the Java main method and implement com.nomagic.magicdraw.commandline.CommandLine#execute
Plugin related batch program:
A program that can call/depend on any running modeling tool plugin
- com.nomagic.magicdraw.commandline.action - specifies the batch mode action (implementation of com.nomagic.magicdraw.commandline.CommandLineAction) you want to execute, for example, -Dcom.nomagic.magicdraw.commandline.action=com.nomagic.magicdraw.examples.commandlineplugin.CommandLineActionExample
- Must launch using com.nomagic.magicdraw.commandline.CommandLineActionLauncher
- The CommandLineAction must be registered in CommandLineActionManager.getInstance().addAction(new CommandLineActionExample()); e.g. in your plugin init() method
- The plugin where CommandLineAction is registered, must load and run, in order for the command line program to launch it. (this means plugin.xml and plugin .jar files must be in the /plugins directory)

The implemented examples can be found in :

Core batch program: <modeling tool installation directory>\openapi\examples\imagegenerator
Plugin batch program: <modeling tool installation directory>\openapi\examples\commandlineplugin

The examples of complete command lines that launches the batch mode programs:

You can modify the previous examples and create more sophisticated batch files. For example, you can define the directory to run the tool from, or specify to use the same java, as the tool uses itself. The exemplary scripts that can be used to start the command line program are shown in the following script examples. The scripts read and use the same classpath as the modeling tool when launching it manually(this is the preferred way to define classpaths).

These scripts can be launched from any directory. Can be modified to read other properties files (e.g. csm.properties, cea.properties)
