File .asm does not exist - atl transformation

Question

i am trying to do the sample transformation given in atl docu. but i am facing the problem once i run the transformation: File family2person.asm does not exist i dont have any clue what this means. i googled and found that .asm has something to do with assembler language. can anyone help me please, since atl is not that widespread language, forums cannot help me now. first i began the tutorial, then i renamed the .ecore files on the way, can that be the reason? trying to find the original asm file having another one in the hand?

thanks a lot

Answer 1

I had the exact same problem; to solve it, I just created a new ATL-Project, copied the ecore metamodels that I had previously created and then, after creating the "family2person.atl" file, the .asm appeared by itself. From the documentation, it seems that this file is just a compiled version of the ATL file that you create, and is only generated when the atl you provide is correct ( although you should also make sure that your .ecore files pass the validation processes .... mine didn't and I had to adjust the cardinalities of some references, specially the EOpposite ones) ... check out this link, to find some more detailed technical info http://wiki.eclipse.org/ATL/User_Guide_-_The_ATL_Tools#Compiling_an_ATL_file.

You can do it within your existing project. Create a new ATL project, open the .project file and copy the stuff there in your main project's .project file. (You'll probably need to close and reopen the project in eclipse)

In my case, the relevant stuff was, in the <natures> section:

<nature>org.eclipse.m2m.atl.adt.builder.atlNature</nature>

and in the <buildSpec> section:

<buildCommand>
    <name>org.eclipse.m2m.atl.adt.builder.atlBuilder</name>
    <arguments>
    </arguments>
</buildCommand>
