The license file should still be installed in (or linked from) /usr/share/licenses/python-pymctranslate. It's only a change in location that led to a packaging error. This is the correct location:

local _site_packages=$(python -c "import site; print(site.getsitepackages()[0])")
local _license_path="${_site_packages}/${_name,,}-${pkgver}.dist-info/licenses/LICENSE"

I am getting the same failure that Moilleadoir is getting.

After sudo pacman -Rsn amulet-map-editor and rebuilding I still get this error with python-pymctranslate

Successfully built pymctranslate-1.2.30-py3-none-any.whl
==> Entering fakeroot environment...
==> Starting package()...
License file not found
Failed to build python-pymctranslate

For me python-amulet-nbt now fails with

  File "/usr/lib/python3.13/site-packages/amulet/api/wrapper/format_wrapper.py", line 25, in <module>
    import PyMCTranslate
ModuleNotFoundError: No module named 'PyMCTranslate'
==> ERROR: A failure occurred in build().
    Aborting...

and python-pymctranslate fails with

Successfully built pymctranslate-1.2.30-py3-none-any.whl
==> Entering fakeroot environment...
==> Starting package()...
License file not found
Failed to build python-pymctranslate

You seem to be trying to build python-pymctranslate-git, this page is for python-pymctranslate. Anyway, I can't reproduce your error with python-pymctranslate-git either, make sure you've installed python-amulet-nbt first. Note that python-pymctranslate-git is currently broken upstream so you won't be able to build it even without the ImportError, see https://github.com/gentlegiantJGC/PyMCTranslate/issues/44

Getting an error in the first test:

Successfully built PyMCTranslate-1.2.22+5.g040384c5.dirty-py3-none-any.whl
