[Acceleo] Error launching main module as Acceleo Application [message #933114]

Dear all,

I'm starting a new Acceleo project and whenever I try to launch a main module as an Acceleo application I get the following error in the log:

Quote:

Message: Couldn't load class dsl3s.templates.Main from project DSL3S

Exception Stack Trace:
An exception stack trace is not available.

Session Data:
eclipse.buildId=M20110909-1335
java.version=1.6.0_26
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US
Framework arguments: -product org.eclipse.epp.package.java.product -product org.eclipse.epp.package.java.product -product org.eclipse.epp.package.java.product
Command-line arguments: -os linux -ws gtk -arch x86 -product org.eclipse.epp.package.java.product -product org.eclipse.epp.package.java.product -data /media/Data/users/lads/Trabalho/Eclipse/Workspace.DSL3S -product org.eclipse.epp.package.java.product

This happens with all main modules in the project. I have verified that all packages containing main modules are exported in the MANIFEST file.

I understand there is little information here. How can I provide more useful details?

Thank you,

Luís

Hello again,

Here in attachment goes a fresh Acceleo project that reproduces the error. If I try to launch the module test.mtl I get the error in the previous message. At the same time I'm getting also this warning:

Quote:

Message: Couldn't load class test.Test. Check that its containing package is exported.

Exception Stack Trace:
An exception stack trace is not available.

Session Data:
eclipse.buildId=M20110909-1335
java.version=1.6.0_26
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US
Framework arguments: -product org.eclipse.epp.package.java.product -product org.eclipse.epp.package.java.product
Command-line arguments: -os linux -ws gtk -arch x86 -product org.eclipse.epp.package.java.product -data /media/Data/users/lads/Trabalho/Eclipse/Workspace.DSL3S -product org.eclipse.epp.package.java.product

But as you can see in the project the export is there:

Export-Package: New.common

Besides this I can't provide much more information besides the software versions:

  Acceleo	3.3.0.v20120529-1042	org.eclipse.acceleo.feature.group	Eclipse Modeling Project
  MDT Papyrus - SDK: Runtime, Tools, Documentation and sources (Incubation)	0.8.1.v201109161105	org.eclipse.papyrus.sdk.feature.group	Eclipse Modeling Project

Eclipse:
Version: Indigo Service Release 1
Build id: 20110916-0149

Needless to say that I can't do any work with Acceleo right now. Please help.

Luís

Hi

If you look at the bottom of the auto-generated Test.java you will see
some instructions on how to register packages such as UML. Try following
them.

Regards

Hi Ed, thank you once again for your help. For future reference here's the line I added to the registerResourceFactories method:

resourceSet.getResourceFactoryRegistry().getExtensionToFactoryMap().put("New.common", New.common.Test.this);

Regards.

Hi

Your line looks extremely suspect:

"New.common" is not an extension such as "*.common".

New.common.Test.this is unlikely to be a Resource Factory.

So you can probably delete the line because it does nothing.

My apologies for the belated response.

Actually the template started running after including that, so it might do something after all...

In any case, given the project I attached here, what would be the correct content of this line?

Thank you.
