## Everything is Optional

Each component in the new installer is optional. Users can install the component defined in the new installer,
use the equivalent component in `istio-system`, configured with the official installer, or use a different
version or implementation.

For example, you may use your own Prometheus and Grafana installs, or you may use a specialized/custom

                }
                getLogger().debug(message);
            } else {
                // Locally installed file is newer, don't use the resolved version
                getLogger().debug(artifact.getArtifactId() + ": using locally installed snapshot");
            }
        }
        return version;
    }

## Prerequisites

- Prometheus and MinIO configured as explained in [document here](https://github.com/minio/minio/blob/master/docs/metrics/prometheus/README.md).
- Grafana installed as explained [here](https://grafana.com/grafana/download).

## MinIO Grafana Dashboard

1. Run tests.
- Run `./gradlew :<subproject>:quickTest` where `<subproject>` is the name of the subproject you've changed. 
- For example: `./gradlew :launcher:quickTest`.
2. Install Gradle locally and try out a change in behavior manually. 
- Install: `./gradlew install -Pgradle_installPath=/any/path`
- Use: `/any/path/bin/gradle taskName`.

                            } else {
                                logger.warn(
                                        "Artifact {}:{}"
                                                + " JAR (about to be installed/deployed) contains Maven Plugin metadata for"
                                                + " conflicting coordinates: {}:{}."
                                                + " Your JAR contains rogue Maven Plugin metadata."

    'Form data requires "python-multipart" to be installed. \n'
    'You can install "python-multipart" with: \n\n'
    "pip install python-multipart\n"
)
multipart_incorrect_install_error = (
    'Form data requires "python-multipart" to be installed. '
    'It seems you installed "multipart" instead. \n'
    'You can remove "multipart" with: \n\n'
    "pip uninstall multipart\n\n"
    'And then install "python-multipart" with: \n\n'

 * h3. create an isolated classloader
 *
 * h3. lookup the plugin with a configuration
 *
 * h3. execute the plugin
 *
 * h3. plugins may have to deal with particular actions when a plugin is - installed - loaded -
 * unloaded - update - uninstalled
 *
 * h3. plugins should be able to have specific metadata for a plugin model and that be translated -
 * dependencies - resources - configuration - extension points of plugins

## Install `PyJWT`

We need to install `PyJWT` to generate and verify the JWT tokens in Python.

Make sure you create a [virtual environment](../../virtual-environments.md){.internal-link target=_blank}, activate it, and then install `pyjwt`:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

In versions below Python 3.9, you import `Annotated` from `typing_extensions`.

It will already be installed with **FastAPI**.
