[MWE2] How to run from command line? [message #546510]

Hello all,

somehow I can't figure out the proper way to run an MWE2 from the
command line on my Linux system, using Eclipse Helios:

java -Xms128m -Xmx1024m -XX:MaxPermSize=256m -jar
/local/dhendriks/eclipse/plugins/org.eclipse.equinox.launche r_1.1.0.v20100507.jar
-nosplash -application org.eclipse.emf.mwe2.launch.runtime.Mwe2Runner
<absolute path to my mwe2 file parent dir>/GenerateCifText.mwe2

When I execute this line from the command line, it thinks for about a
second and then returns to the prompt. There is no output, and it didn't
generate the code using the xtext file (that's what the MWE2 is supposed
to do).

Obviously everything works just fine from Eclipse UI.

Does anyone know what I'm doing wrong?

Thanks,
Dennis

Unfortunately, this procedure does not work (for me). The problem is that
some emf code needs some properties form a plugin.properties file:
ERROR eclipse.emf.mwe.core.WorkflowRunner
- The string resource '_UI_DiagnosticRoot_diagnostic' could not be located

So, the trick is to add a plugin.properties to the generated .jar file that
fixes the problem.

I use 7zip to add a .properties file.

I generate the plugin.properties file by:

- do the export above but this time I select
"Copy the required file into a sub-folder next to the generated JAR"
- then I extract all jar files (using 7zip) into one folder but
with auto-rename all duplicate files
- cat all plugin*.properties file into one

I hope this helps

Michael

Hello,

some more searching turned up
http://blogs.itemis.de/feltes/2010/07/02/how-to-run-xtext-an d-other-mwe2-workflows-with-ant/,
which refers to the
http://zarnekow.blogspot.com/2010/06/how-to-deploy-xtext-sta ndalone.html
page, and explains how to do xtext/mwe2 from Ant scripts. It worked for me.
