[ATL] Question about using superimpose in Ant files [message #499324]

Hey,

I have one question, I hope that some of you can help me! Smile

I'm trying to automate my ATL transformation using Ant. But it is not working!

The build file that I'm trying to execute is the following :
<?xml version="1.0" encoding="UTF-8"?>
<project name="Phase1" default="run" basedir=".">
<property name="atl.launcher" value="Regular VM (with debugger)"/>
<property name="sourcePath" value="../sourcemodel/MasterProject.uml" />
<property name="resultPath" value="../result/result.xmi" />

<property name="metricsCalcPath" value ="../transforms/metricsCalc.asm"/>
<property name="ignoreBadSmellsPath" value ="../transforms/ignoreBadSmells.asm"/>
<property name="functionsLibPath" value ="../transforms/functionsLib.asm"/>
<target name="run">
<atl.loadModel name="Source" metamodel="MOF" nsUri="http://www.eclipse.org/uml2/2.1.0/UML" />
<atl.loadModel name="QueryResult" metamodel="MOF" path="../metamodel/BSDMC_MM.ecore"/>
<atl.loadModel name="sample" metamodel="Source" path="${sourcePath}" />
<atl.launch path="../transforms/phase1.asm">
<inmodel model="sample" name="IN" />
<outmodel model="OutModel" name ="OUT" metamodel="QueryResult" />
<library name="functionsLib" path="${functionsLibPath}" />
<superimpose path="${metricsCalcPath}"/>
<superimpose path="${ignoreBadSmellsPath}"/>
</atl.launch>
<am3.saveModel model="OutModel" path="{resultPath}"/>
</target>
</project>

If I try to run it, it loads the 3 models correctly, then tries to execute the atl.lauch generating one error : java.lang.NullPointerException.

I think that it has something to do with the use of superimpose, if I remove the superimpose declarations, an error message is generated informing that a operation in my transformation is missing. (This operation is implemented in the removed superimpose file. Smile

)
If I run it without Ant it works just fine! Very Happy

Do you known what I may be doing wrong? Smile

Thanks a lot in advance,

Lucas

P.S.: ATL Version : 3.0.1.v200909220532
The Public2Private build file works fine here!

Hey again! Smile

If I remove the superimpose, and copy all content from the superimposed modules to the transformation file (phase1.asm) it works fine.
I've also changed <am3.saveModel model="OutModel" path="{resultPath}"/> by
<atl.saveModel model="OutModel" path="{resultPath}"/>

I would like to use superimpose. So I can divide all my rules by modules. Razz

I'm still trying to find out what is wrong here! If you have any idea I would be glad to here it!

Thanks again in advance!

Have you try to use superimpose with hand launch first ?
The organisation of superimpose use is not trivial and you may first
learn about it before automating it.

Hey Vincent,

first of all thanks for the reply! Smile

Without using Ant (By hand), it works perfectly! Razz

I have a similar problem, trying to use the UML2Profiles example mentioned in the ATL User Guide. Using the launch configuration, it works. Using an ant build script:

<?xml version="1.0"?>
<project name="mod2core_controlvars" default="run" basedir=".">
    <property name="inpath" value="../models/JavaTypes.uml"/>
    <property name="outpath" value="../models/JavaTypes2b.uml"/>

    <property name="atl.launcher" value="Regular VM (with debugger)"/>

    <target name="run">
        <atl.loadModel metamodel="%EMF" name="UML2" path="../metamodels/UML2Profiles.ecore"/>
        <atl.loadModel metamodel="UML2" name="inmodel" path="${inpath}"/>
        <atl.loadModel metamodel="UML2" name="accessors" path="../profiles/Accessors.profile.uml"/>
        <atl.launch path="../UML2Copy.asm">
            <!--superimpose path="../UML2Profiles.asm"/-->
            <library name="UML2" path="../lib/UML2.asm"/> 
            <inmodel name="IN" model="inmodel"/>
            <inmodel name="ACCESSORS" model="accessors"/>
            <outmodel name="OUT" model="outmodel" metamodel="UML2"/>
        </atl.launch >
        <atl.saveModel model="outmodel" path="${outpath}"/>
    </target>
</project>

without superimposition (note the commented out superimpose) it works (although it is just a copy, as it uses only UML2Copy.asm).

When I enable the superimposition, I get:

BUILD FAILED
XXX/superimpose_test/launch/build.xml:12: java.lang.NullPointerException

Does anyone know how to fix this? As seen at http://soft.vub.ac.be/viewvc/UML2CaseStudies/uml2cs-instantm essenger-model/outmodels/common/build.xml?view=markup&pa threv=5633 it should work (assuming that the example worked for someone). But they use am3 tasks, and not atl tasks. Also, I couldn't find how to check out that entire example repository, so I donwloaded just the files I needed and created my own ant build script, inspired by the example.

Seeing as the original poster got the same error, I wonder if anyone knows what we both did wrong? Any help would be greatly appreciated!

I believe there was a bug with super-imposition in ant scripts. It was corrected I think but i don't know in which version.

Thanks for the quick reply.

I'm using eclipse-modeling-galileo-SR1-incubation-linux-gtk.tar.gz as my Eclipse version. I think that's the latest version, except for cvs versions. Was it fixed very recently or before galileo SR1?

Just to let you know, it works again in Galileo SR2. Thanks again!

hi all

and I have some questions if you kindly can answer them

what is the need of the superimpose in the Ant file, what I understand
is that it enforces second transformation file after the first one, I am
speaking about the UML2Profile use case not the above code as I could
not understand it all.

the second is that is there an editor which facilitates the ant build
task completion as I know only the mentioned in the ATL tutorial and it
is not enough as I deduced later.

For more information on ATL superimposition: http://wiki.eclipse.org/ATL_Superimposition

Basically, the rules of one file overwrite the rules of another. Superimposition has nothing to do with Ant scripts, you can use it in ATL launch configurations as well.
