Hi,

I would know if it there is a mean for recompile acceleo modules (*.mtl) outside Eclipse.

Thanks,

Hello,
compilation outside Eclipse is possible.
However, it is not documented and not trivial.
I think you should ask for help to Obeo

Hi,

As Sebastien mentioned, standalone compilation is possible ... but
you'll have to get your hands dirty.

In short, we defined an ANT task in the plugin
'org.eclipse.acceleo.parser' that you can use for standalone
compilation. This task is located in the "acceleoCompiler" jar file that
you can retrieved here :
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2t/org .eclipse.acceleo/plugins/org.eclipse.acceleo.parser/lib/acce leoCompiler.jar?revision=1.6&root=Modeling_Project
..

You can use this ANT task with the following : <acceleoCompiler
sourceFolders="path1;path2;path3....."/>

For example, here is how we use it in the Eclipse builds :
<target name="post.gather.bin.parts">
<acceleoCompiler sourceFolders="${target.folder}"/>
</target>

You'll need to have the proper classpath defined to use this; at the
very least
org.eclipse.acceleo.common
org.eclipse.acceleo.model
org.eclipse.acceleo.parser
org.eclipse.core.runtime
org.eclipse.emf.ecore
org.eclipse.emf.ecore.xmi
org.eclipse.ocl
org.eclipse.ocl.ecore

If you wish to recompile mtl files through pure java instead of using
ANT, you'll have to take a look at the AcceleoCompiler task source code
:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.m2t/org .eclipse.acceleo/plugins/org.eclipse.acceleo.parser/src-ant/ org/eclipse/acceleo/parser/compiler/AcceleoCompiler.java?rev ision=1.13&root=Modeling_Project&view=markup

And reproduce something similar.

Hi,

Thank you for your answers.

Laurent, I get dirty hands, for sure Smile

, but my goal is to make the whole process of generation outside Eclipse.

On this point precisely, I have a problem compiling modules. I get the following error by launching AcceleoCompiler (with ant and standalone execution):

Hi,

This error is due to missing URI mappings and package registrations (all
of these are normally taken care of by Eclipse, yet you are in standalone).

Namely, you need to add the URI mappings for our libraries (this is the
source of the exception you copy/pasted here) :
URIConverter.URI_MAP.put("http://www.eclipse.org/acceleo/mtl/3.0/mtlstdlib.ecore",
" platform:/plugin/org.eclipse.acceleo.model/model/mtlstdlib.e core ");
URIConverter.URI_MAP.put("http://www.eclipse.org/acceleo/mtl/3.0/mtlnonstdlib.ecore",
" platform:/plugin/org.eclipse.acceleo.model/model/mtlnonstdli b.ecore ");

and afterwards, you'll most likely have exceptions of type "package with
URI '*' not found. Take a look at
http://eclipsemde.blogspot.com/2010/06/package-with-uri-not- found.html
for explanations on the source and solution of these if you encounter them.

Sorry, my bad. The URI Mappings to register of course aren't
"platform:/plugin" as those URIs are eclipse specific and absolutely not
standalone.

Sebastien Roy faced the same problems as you, and managed to single out
the URI mappings and diverse registrations to the following few (Java
code) :

-----8<-----

Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "ecore",
new EcoreResourceFactoryImpl());
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "emtl",
new EMtlResourceFactoryImpl());
// Uncomment if you need to use UML
//
Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap( ).put( "uml",
UMLResource.Factory.INSTANCE);

// Uncomment if you need to use UML
// EPackage.Registry.INSTANCE.put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
// Uncomment if you need to use an UML model created with an old version
of MDT/UML
//
EPackage.Registry.INSTANCE.put("http://www.eclipse.org/uml2/2.1.0/UML",
UMLPackage.eINSTANCE);

CodeSource acceleoModel =
MtlPackage.class.getProtectionDomain().getCodeSource();
if (acceleoModel != null) {
String libraryLocation = acceleoModel.getLocation().toString();
if (libraryLocation.endsWith(".jar")) {
libraryLocation = "jar:" + libraryLocation + '!';
}
URIConverter.URI_MAP.put(URI.createURI("http://www.eclipse.org/acceleo/mtl/3.0/mtlstdlib.ecore"),
URI.createURI(libraryLocation + "/model/mtlstdlib.ecore"));
URIConverter.URI_MAP.put(URI.createURI("http://www.eclipse.org/acceleo/mtl/3.0/mtlnonstdlib.ecore"),
URI.createURI(libraryLocation + "/model/mtlnonstdlib.ecore"));
} else {
System.err.println("Coudln't retrieve location of plugin
'org.eclipse.acceleo.model'.");
}

----->8-----

Thanks to Sebastien Roy for sharing his solution :).

Hello,

Even if the compilation works fine with the code above, I currently have a problem with Maven and the AcceloCompiler classpath :

I created a project containing a class that inherits from acceleo compiler and that performs all needed registrations before execution.
I put all accelo, emf, uml, ... dependencies in the dependencies of the project.
In all my acceleo projects, I created a antrun-plugin section that define a taskdef using my compiler class

My problem is that the classpath given to my compiler class contains only de compiler dependencies, not the compiled project dependencies.

Does someone know how to add the project dependencies to the compiler classpath ?

Regards

Sebastien

Hello ,

Thanks to Laurent ans Sebastien, I solved the problem by following your indication.

To Sebastien. I use maven for whole generation process, and this work fine.
I do not see why you want add the dependences of your to those of the compiler, but I can alway show you how I proceded :

I packaged the Acceleo compiler in maven plugin
Then I included the Acceleo compiler plugin in my Acceleo project builded with Maven.

As you can see, with this choice, the Acceleo compiler don't need Acceleo projects dependencies.

Hello,

Thank your for your advice. I will try creating a maven plugin instead of the ant task.
Actually, the compiler must be aware of the acceleo dependencies only when there are mtl imports from outside the currently compiled project. If all the imported mtl modules are defined inside the project, there will not be any problem, in any case.

I will keep you informed.

Hello,

When you said "dependencies", I didn't thought to mtl depencies, because all templates I import actually are internal to my project.

Else, for mtl external dependencies resolution, you know probably, you should rather examine the compiler "computeDependencies" method.

Think you for keep me informed.

Hello Aboubakar,
I've just created a maven plugin for Accelo Compiler.

I have the same problems than with the ant task : the maven doesn't add the compiled project dependencies to the class path. The class path only contains the copiler dependencies.

Do you know how to add these dependencies to the classpath ?

Sebastien, aboubakar,

I don't think maven experts will read this thread, you might be able to
get some help on this on the tycho newsgroup (maven integration with OSGi)?

I don't know if you'll get an answer as this is maven specific and not
tycho related but I know for sure that I cannot answer :p.

Hello Sebastien,

As I said , I don't understand why the compiler must have the compiled project dependencies. The compiler need only the root directorys containing mtl files, alright ? And if your mtl modules have eventual dependencies to emtls , we must also give to compiler directorys containing these emtls.

For example, in my maven generation project pom, I use the Acceleo compiler packaged in maven plugin like this ( my templates are in /src/main/java folder ) :

			<plugin>
				<groupId>north.org.eclipse.acceleo</groupId>
				<artifactId>acceleo-compiler</artifactId>
				<version>1.0.0-SNAPSHOT</version>
				<configuration>
					<sourceFolders>
						<param>${basedir}/src/main/java</param>
					</sourceFolders>
				</configuration>
				<executions>
					<execution>
						<goals>
							<goal>acceleocompile</goal>
						</goals>
					</execution>
				</executions>
			</plugin>

But maybe I still do not understand your problem ?

Hello Aboubakar,

My problem is that I want to make and use a library of mtl modules. I wrote a set of generic queries, generic transformations that I want to use in several target projects. So all the imported mtl modules are not defined in the currently compiled project. Some are defined in external libraries

Into Eclipse environment it's easy, just export the common package of the library and import them in the target project. Osgi mechanisms are very powerfull.

In standalone compilation, the first step would be to put in the classpath of the compiler the jar file of my external mtl library. That is my current problem

Hello Sebastien,

Your problem is now clear to me. If your goal is to put the compiled project dependencies into the Acceleo compiler plugin's classpath, I suggest you to follow these steps at Acceleo compiler launching:

retrieive the paths of all compiled project dependencies and stock them,
stock the plugin dependencies path also ,
Launch a external JVM process to run Acceleo Compiler process. For this JVM classpath, you will give all you want, in all case the compiled project and the compiled dependencies.

( Remarks that the Maven Compiler Plugin should certainly perform a similar process for compile our projects ).

I dont guaranted you that my suggestion will work, but I can assure you that a I done a elementary manipluation of POM of the compiled project in my plugin with succes.

Hello Aboubakar,
The exec-maven-plugin looks great. Thank you very much for your feed back.
How did you implement it ? You created a class with a main() method in charge of calling the acceleo compiler ?

As my problem is not solved yet (I still copy my dependencies in each project that need them), I really appreciate your help.
I'm going to try this solution soon.

@Charlie : I'm also interested in your sources. I think it would be helpfull for all the community.

It's nothing : ) ,
I just use the plugin for the moment to start a Java main class.

Here is a sample usage ( the 2nd sample ) : http://mojo.codehaus.org/exec-maven-plugin/usage.html

I hope it will work.

Hello Aboubakar,

The exec-maven-plugin works perfectly : I can use it to launch the MtlCompiler with all project dependencies present in the classpath.

However, when I remove the copy of my dependencies, the AcceleoCompiler is not able to find them into the classpath.

I am very disapointed !!!

Now the answer to the problem has to be brought by Acceleo team...
