how to overwrite workflow properties: headless code generation with mwe2 [message #558844]

Hello,

I start an MWE2-workflow from the command line with the class
org.eclipse.emf.mwe2.launch.runtime.Mwe2Launcher.

Everythings works fine, but...

The workflow contains some properties which I want to customize
(overwrite) whith model dependend values, e.g. a model path.

How can I replace the properties of the workflow with parameters from
the command line?

Any help is appreciated.

Thanks a lot,

Stefan

Hi,

thanks, but the class Mwe2Launcher does not allow more than the one
parameter for the name of the workflow module:

if (line.getArgs().length > 1)
throw new ParseException("Only one module name expected. But " +
line.getArgs().length
+ " were passed (" + line.getArgList() + ")");

I solved the problem by rewriting the Mwe2Launcher without this restriction.

Please let me know if there is a better solution.

Thanks,

Stefan

Hi,

a little hint:

Mwe2Launcher.main(new String[]{"src/workflow/test.mwe2","-p","variable=test"});

Works fine using Xtext / Mwe2 1.0.1
