+**_NOTE:_** it is not possible to invoke _Prettier-Java_ in your IDE without creating a `package.json` file unless you use an alternative to `npx` like [prettier-pnp](https://github.com/auvred/prettier-pnp) due to the way plugins are loaded. Further, _Prettier_ [recommends that the exact version of prettier be set and locked](https://prettier.io/docs/en/install) on a per-project basis, as formatting preferences change from version to version.
