[ATL] Cannot import EMFTVM [message #1034299]

Hi members,

I'm currently trying to switch from the 'normal' ATL compiler to EMFTVM, as it seems to be much faster and gives clearer error hints.
My problem: I cannot import the stuff suggested here. EmftvmFactory, for example, is not available in my Juno's type browser (CTRL+SHIFT+T), although version 3.3.1 of the ATL SDK is installed and

-- @atlcompiler emftvm

in the ATL file works no problem.
Can you give me any hint what I am missing? Thanks!

Did you add the org.eclipse.m2m.atl.emftvm plug-in to your dependencies? Are
you writing an Eclipse plug-in or a standalone Java application? If the
latter, please also check http://wiki.eclipse.org/ATL/EMFTVM#Standalone_use

Kind regards,
Dennis

Dennis, thanks again. The plug-in org.eclipse.m2m.atl.emftvm is not available in my target platform or type browser. I have installed the ATL SDK from http://download.eclipse.org/releases/juno in both Eclipse itself and the target platform.
Do I need anything else in order to use EMFTVM in a plug-in (it is not standalone)? As mentioned before, the EMFTVM compiler is available and works fine.

As you've got EMFTVM working at design-time, I'll assume you've got the EMFTVM
feature and all its plug-ins installed correctly. That does not make it
available to your own plug-in, however. Eclipse plug-ins (or OSGi bundles in
general) require you to explicitly list the dependencies.

You need to specify "org.eclipse.m2m.atl.emftvm" as a dependency in your
plug-in's MANIFEST.MF. Example:

Require-Bundle: org.eclipse.core.runtime,
org.eclipse.m2m.atl.common,
org.eclipse.m2m.atl.emftvm

Eclipse also provides a graphical editor for the MANIFEST.MF file, where you
can add the required plug-ins under the "Dependencies" tab.

Kind regards,
Dennis

Dennis, thanks once more. I know that I have to add the plug-ins, but they are not available. See the the screenshot of the available plug-ins

As you can see, ATL SDK 3.3.1 is installed. Are you sure that I don't need anything else?

I think I know what might have caused confusion:
http://wiki.eclipse.org/ATL/EMFTVM#Installation lists two installation sources
for EMFTVM, but both sources contain EMFTVM **as a separate feature** and not
as part of the ATL SDK.

Dennis, I had indeed missed that and have installed the EMFTVM feature.

But the bundles still are not available, although the EMFTVM jars are in my Eclipse's plugins folder.

[UPDATE] I've added the plug-ins to the target platform, they seem to be available now.

Dennis, thanks to your help, I finally got it working. One problem remains: EMF2.5 and, thus, Eclipse core runtime 3.5 is required, but I use it in a project based on Eclipse 3.4. Guess I'll have to stick to the standard vm Sad

I just regenerated EMFTVM's metamodel with EMF 2.4 compatibility set. Turns
out it makes no difference, and the exact same code comes out. I will just
reduce the required version down from 2.5 to 2.4. New snapshot release coming
up...
