`dev-pypi` is repeatedly added to `uv` `pyproject.toml` files, making it impossible to use a dev repository

[d-ryan-ashcraft]

When a uv project is configured to leverage useDevRepository:

                <plugin>
                    <groupId>org.technologybrewery.habushu</groupId>
                    <artifactId>habushu-maven-plugin</artifactId>
                    <version>${version.habushu.plugin}</version>
                    <extensions>true</extensions>
                    <configuration>
                        <pythonVersion>${version.python.default}</pythonVersion>
                        <useDevRepository>true</useDevRepository>
                    </configuration>
                </plugin>

Running deploy results in triplicates of the dev-pypi configuration in my pyproject.toml file:

[[tool.uv.index]]
name = "dev-pypi"
url = "https://test.pypi.org/simple/"
publish-url = "https://test.pypi.org/legacy/"
[[tool.uv.index]]
name = "dev-pypi"
url = "https://test.pypi.org/simple/"
publish-url = "https://test.pypi.org/legacy/"
[tool.ruff.format]
indent-style="space"
line-ending="lf"
quote-style="preserve"

[dependency-groups]
dev = [
    "ruff>=0.9.10",
]


# Added by habushu-maven-plugin at 2025-06-18T11:45:31.764463 to use https://test.pypi.org/simple/ as source PyPi repository for installing dependencies
[[tool.uv.index]]
name = "dev-pypi"
url = "https://test.pypi.org/simple/"
publish-url = "https://test.pypi.org/legacy/"

The resulting deploy-time error is:

This is happening with Habushu 3.1.0.

Looks like this is caused by a bug in tomlkit. We use toml-cli to set the project version to a timestamped version, which in turn uses tomlkit to parse and update the toml file. Because of the bug, every time the toml file is written, the dev-pypi definition is duplicated.

A workaround is to ensure that all [[tool.uv.index]] tables are grouped together.
