Hi all,

I am using Acceleo since a year ago. However, now I am facing a problem I can not solve. This problem is related to module imports, which are resolved during edition (no sintax errors are highlighted), but in compilation time I get this error:

Errors occurred during the build.
Errors running builder 'Acceleo Builder' on project 'org.eclipse.acceleo.qt_test_api.generator'.
org.eclipse.core.internal.resources.ResourceException: Resource '/testapi_generator/bin/org/eclipse/acceleo/qt_test_api/generator/common/generate.emtl' does not exist.

However, this compiled file called "generate.emtl" actually exists, as you can see in the attached figure. Some additional data that may be useful to understand the problem are:
- template with the main annotation: mainGenerate.mtl
- secondary template without main annotation: generate.mtl
- no errors in sintax
- all emtl files are generated, even after cleaning and rebuilding the project
- building project is set to automatic
- F5 + clean + rebuild 'magic trick' does not work

Many thanks in advance for your help and time

Definitely I think I solved the problem.

Acceleo requires that the name of your project in your workspace (i.e., the one you can see in the Package Explorer in the left tab in Eclipse) needs to be EXACTLY THE SAME as the name of the folder containing the project in your file system.

It seems that Acceleo compiler uses the name in the workspace instead the real containing folder's name during compilation, which may be a bug of the compiler since Acceleo projects with a different name are not allowed.
