EMF generated projects don't compile [message #660333] Thu, 17 March 2011 23:35 Go to next message

I have a, say, "example" project that contains a .genmodel file that validates without errors nor warnings.
When I select the topmost element and select "Generate All" I get an "example.edit" project that compiles fine plus a
"example.editor" project that has >200 errors and doesn't compile, apparently mostly due to one or more missing imports of
org.eclipse.swt.X (where X is "SWT", "event", "layout" and "widgets"). How do I convince EMF to generate projects that *do* compile?

This is on Helios v3.6.2 (Build id: M20110210-1200) on top of Windows 7.

Michael,

EMF didn't change in 3.6.2. I've not heard of anyone else having this
problem. It seems like a glaring issue, not a subtle one, so I'd expect
all to notice it immediately. Unless of course it's specific to your
setup...

Are you saying the imports are absent from the .java files? Or they're
there, but they don't resolve because the dependency on org.eclipse.swt
is not properly resolved?

Hi Michael

EMF has incremental merged generation for Java files but leaves a
pre-existing MANIFEST.MF unchanged.

Is it possible that an early generation attempt or manual intervention
created an inadequate MANIFEST.MF?

I suggest that you delete your editor project so that EMF can generate
afresh.

Regards

Ed Willink

The latter, i.e. already those imports don't resolve.

I deleted the MANIFEST as well as the generated model code, i.e. I restarted from a clean slate and empty project just keeping the
..ecore and the .genmodel file and then issued a "Generate All".

The result is
the src tree in the example project - compiles
example.edit project - compiles
example.editor project - does not compile - see below
example.test project - compiles

The example.editor project contains four files

package example.presentation:
ExampeModelActionBarContributor
ExampleModelEditor
WebPullModelEditorPlugin
WebPullModelModelWizard

Except for the ...Plugin file all other files show compile errors and have issue with their import statements
import org.eclipse.swt.<X>;

and of course there are errors in all lines that reference any SWT class or item.

The top line of those files also has a marker that reads e.g.:

Multiple markers at this line
- The type org.eclipse.swt.widgets.Tree cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.events.ControlAdapter cannot be resolved. It is indirectly referenced from
required .class files
- The type org.eclipse.swt.widgets.Table cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.widgets.Menu cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.dnd.DragSourceListener cannot be resolved. It is indirectly referenced from
required .class files
- The type org.eclipse.swt.widgets.List cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.dnd.DropTargetAdapter cannot be resolved. It is indirectly referenced from
required .class files
- The type org.eclipse.swt.custom.TreeEditor cannot be resolved. It is indirectly referenced from required .class
files
- The type org.eclipse.swt.dnd.DropTargetListener cannot be resolved. It is indirectly referenced from
required .class files
- The type org.eclipse.swt.dnd.ByteArrayTransfer cannot be resolved. It is indirectly referenced from
required .class files
- The type org.eclipse.swt.dnd.Transfer cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.graphics.Point cannot be resolved. It is indirectly referenced from required .class files
- The type org.eclipse.swt.custom.CTabFolder cannot be resolved. It is indirectly referenced from required .class
files

What the heck am I missing?

Michael,

Perhaps SWT isn't in your target platform? It is possible to add SWT as
a direct dependency in your manifest? You shouldn't need it because the
EMF's bundles re-export it, but it will be a good test to try.
