Hi,

I'm trying to programmatically launch an ATL transformation. I'm using
Eclipse 3.3.1.1 (JDK 1.5.0) and downloaded into it all available plugins
from the update site at
http://download.eclipse.org/modeling/m2m/atl/updates/2.0.0

When I write this code into a plugin project of mine:

import org.eclipse.m2m.atl.engine.AtlModelHandler;
...
AtlModelHandler modelHandler =
AtlModelHandler.getDefault(AtlModelHandler.AMH_EMF);
modelHandler.getMof();

I get an error from the last line:
"The project was not built since its build path is incomplete.
Cannot find the class file for
org.eclipse.m2m.atl.engine.vm.nativelib.ASMModel.
Fix the build path then try building this project"

The class ASMModel is present in file
plugins/org.eclipse.m2m.atl.engine.vm_2.0.0/org/eclipse/m2m/ atl/engine/vm/nativelib/ASMModel.class
in the Eclipse instance. The plugin org.eclipse.m2m.atl.engine.vm is among
the dependencies of my plugin. But under the plugin properties,
Java Build Path > Libraries > Plug-in Dependencies, no class folder nor a
jar file, corresponding to plugin org.eclipse.m2m.atl.engine.vm, appears.

I find it strange that the file
org.eclipse.m2m.atl.engine.vm_2.0.0/META-INF/MANIFEST.MF
has no Bundle-ClassPath line. Is this normal? Isn't
org.eclipse.m2m.atl.engine.vm meant to export its classes?

When I jar the .class files of this plugin and mention it in a
Bundle-ClassPath line in
plugins/org.eclipse.m2m.atl.engine.vm_2.0.0/META-INF/MANIFES T.MF
the problem goes away.

Hello,

The update site you reference does match an old ATL version, which is no
more maintained. We recently switch to correct build procedures and
freeze the odl ATL version in this "Old downloads" page.

The true download page is available here :
http://www.eclipse.org/modeling/m2m/downloads/index.php?proj ect=atl
and the update sites :
http://www.eclipse.org/modeling/m2m/updates/

I will try to make the old page more clear, thanks for reporting.

Best regards,

William
