The "poetry.dev-dependencies" section is deprecated and will be removed in a future version. Use "poetry.group.dev.dependencies" instead.
Error: pyproject.toml changed significantly since poetry.lock was last generated. Run `poetry lock` to fix the lock file.
Warning: The "poetry.dev-dependencies" section is deprecated and will be removed in a future version. Use "poetry.group.dev.dependencies" instead.
Warning: [tool.poetry.name] is deprecated. Use [project.name] instead.
Warning: [tool.poetry.version] is set but 'version' is not in [project.dynamic]. If it is static use [project.version]. If it is dynamic, add 'version' to [project.dynamic].
If you want to set the version dynamically via `poetry build --local-version` or you are using a plugin, which sets the version dynamically, you should define the version in [tool.poetry] and add 'version' to [project.dynamic].
Warning: [tool.poetry.description] is deprecated. Use [project.description] instead.
Warning: [tool.poetry.readme] is set but 'readme' is not in [project.dynamic]. If it is static use [project.readme]. If it is dynamic, add 'readme' to [project.dynamic].
If you want to define multiple readmes, you should define them in [tool.poetry] and add 'readme' to [project.dynamic].
Warning: [tool.poetry.authors] is deprecated. Use [project.authors] instead.
Warning: [tool.poetry.keywords] is deprecated. Use [project.keywords] instead.
Warning: [tool.poetry.classifiers] is set but 'classifiers' is not in [project.dynamic]. If it is static use [project.classifiers]. If it is dynamic, add 'classifiers' to [project.dynamic].
ATTENTION: Per default Poetry determines classifiers for supported Python versions and license automatically. If you define classifiers in [project], you disable the automatic enrichment. In other words, you have to define all classifiers manually. If you want to use Poetry's automatic enrichment of classifiers, you should define them in [tool.poetry] and add 'classifiers' to [project.dynamic].
Warning: [tool.poetry.homepage] is deprecated. Use [project.urls] instead.
Warning: [tool.poetry.repository] is deprecated. Use [project.urls] instead.
Warning: Defining console scripts in [tool.poetry.scripts] is deprecated. Use [project.scripts] instead. ([tool.poetry.scripts] should only be used for scripts of type 'file').
