The method x() of type y must override a superclass method [message #1740496]

I am using an interface, but for some reason, if I do a clean build (Project -> Clean) an error "The method Dead

) of type y must override a superclass method" occurs. If I "touch" the files that contains the errors, Eclipse automatically builds it again and the error is fixed.

The error type is an "Xtend Problem". Is this an existing bug? What workaround is available for this?

I am not sure if this is relevant but I am using Java1.7 and Xtend version 2.9.1.v201512180746.

Hi Christian,

I have attached the project that reproduces the problems I am seeing.
I am using eclipse-dsl-luna-SR2-win32 with Java 1.7, though I have tried eclipse-dsl-neon-R-win32 and the problem is still there.

The code might not make sense as this is a scaled-down version of the whole project.

Hi, I haven't solved this problem yet. Anyone have any idea how to fix this? Or any workaround available? Smile

welll 7z is a quite unhandy file extension.
unfortunately i dont know how to provoke the error when importing.
can you give more hints where the error happens on your side?

well when doing a clean i get some errors.
seems like xcore+xtend+java dont like each other that much.
it seems to help to separate out the xcore stuff out to a separate bundle.
can you please create a bug
