How to launch the XTend compilation after having generating Xtend code? [message #1402832] Thu, 17 July 2014 17:22 Go to next message

Hi,
I have a DSL, powered by Xtext, that generates Xtend code.
When I edit a model of my DSL the Xtend code is correctly generated in a dedicated folder (different than xtend-gen) but not compiled.
To compile the generated xtend code, I need to open the xtend files, add a space, and save (refresh, clean, and co do not work).

How can I (programmatically) trigger the Xtend compilation after the generation of my code?


Cheers,
ARno

Hi,

what about call the builder (clean build) for the project?
(retrieve the IProject and call build on it?)

I just tried that and it does not work (nothing happens, no error in the error console):

project.build(IncrementalProjectBuilder::FULL_BUILD, null)

My DSL is here:
github.com/arnobl/kompren/tree/master/kompren-editor/fr.inria.diverse.kompren.xtext

project.touch(null) or disabling the auto-build of the project to manually build have no effect. :s

make sure

- you called refresh on the project first
- the project has xtext nature and xtext builder added

The project has the xtext nature and text builder since the xtend files are compiled if a modified them manually.

I tried brutal things:
ResourcesPlugin.getWorkspace().getRoot().projects.forEach[proj|
proj.refreshLocal(IResource.DEPTH_INFINITE, null)
proj.touch(null)
proj.build(IncrementalProjectBuilder::CLEAN_BUILD, null)
]
...
myXtendFile.touch(null)
myXtendFile2.touch(null)

but the xtend files are still not compiled when editing my DSL model.

Is there something to add in the mwe2 or something to bind to chain the xtend/xtext builder to my dsl?

Last question: are the files within a source folder.

Can you give a step by step description on how to reproduce?

Yes, the files are within a source folder.

To reproduce the problem:
1. Download our Eclipse studio (https://ci.inria.fr/diverse-commons/job/diverse-studio/)
2. Download the following project (https://github.com/arnobl/kompren/raw/master/kompren-examples/eclipseProjectTemplate.zip)
3. Import this last as an existing project into our Eclipse studio and move to the Java perspective
4. Open the file mySlicer.kompren
5. Add the line slicedProperty: ecore.ENamedElement.name at the end of this file
-> The compilation process starts: Xtend files are generated into the folder kompren-gen
-> These xtend files are not then compiled in Java code (into the folder xtend-gen)
When opening one of these xtend files to modify it manually, the xtend compilation starts.
Sometimes (very rarely), the xtend files are automatically compiled. I remove the generated Java files to see whether they are re-compiled but nothing happens.

The problem also appears with a standard Eclipse (4.3 and 4.4) supplemented with the required plugins (this is my case). I pointed you our Eclipse studio just to simplify the replication of the problem.

Here (I just commited):
https://github.com/arnobl/kompren/blob/master/kompren-editor/fr.inria.diverse.kompren.xtext/src/fr/inria/diverse/kompren/generator/KomprenGenerator.xtend

The eclipse studio I pointed you does not contain this commit, but it still does not work for me in my dev eclipse.

Ok thx :s
Is that possible to launch the compilation programmatically?
I tried that from lines 62 to 66 in the file KomprenGenerator.xtend (see my previous post) but I get the following error message while the files exist:
org.eclipse.emf.ecore.resource.impl.ResourceSetImpl$1DiagnosticWrappedException: java.io.FileNotFoundException: /KomprenSlicerTemplate/src/main/kompren-gen/myslicer/MySlicer.xtend

I have finally a manual workaround better than modifying the xtend files.
If a remove the source folder that should contain the java files, there are re-generated (it works only when I remove the source folder, ie removing a java package has no effect).
