Then for any subsequent call of `get_settings()` in the dependencies for the next requests, instead of executing the internal code of `get_settings()` and creating a new `Settings` object, it will return the same object that was returned on the first call, again and again.

        return getMavenSession().getSettings().getDelegate();
    }

    @Nonnull
    @Override
    public Collection<ToolchainModel> getToolchains() {
        return getMavenSession().getRequest().getToolchains().values().stream()

都会创建一个新的 `Settings` 对象，并且在创建时会再次读取 `.env` 文件。

如果依赖项函数是这样的：

```Python
def get_settings():
    return Settings()
```

我们就会为每个请求创建该对象，并为每个请求读取 `.env` 文件。 ⚠️

但由于我们在顶部使用了 `@lru_cache` 装饰器，`Settings` 对象只会在第一次调用时创建一次。 ✔️

接着，对于后续请求中依赖项里对 `get_settings()` 的任何调用，它不会再次执行 `get_settings()` 的内部代码并创建新的 `Settings` 对象，而是会一遍又一遍地返回第一次调用时返回的那个相同对象。
