No python files included in test package

[neda-dtu]

I created a small test package for experimenting with rattler-build using the directory structure we use on our internal projects. With this package conda mambabuild is able to create a working package, while rattler-build doesn't include the necessary python files. Below are the lists of files in the tar.bz files.

Thanks for the info, really nice that you shared the test package! We'll take a look!

Hi @neda-dtu thanks for this test package! Very helpful. I've been looking at it and done some debugging.
One of the main problems is that you are using the build environment where you should be using the host environment.

conda-build is doing some workarounds to make it work, but it's better to switch to the new way of doing things. If you just exchange build to host it will start to work in rattler-build, too.

[wolfv]

I can confirm that this works fine when changing build to host. I am going to close this issue for now. Thanks again!

[neda-dtu]

Thanks for the tip. I figured it was something wrong with my configuration. I will reread the documentation about the host and build sections to avoid this issue in the future.
