# Background Tasks - `BackgroundTasks`

You can declare a parameter in a *path operation function* or dependency function with the type `BackgroundTasks`, and then you can use it to schedule the execution of background tasks after the response is sent.

You can import it directly from `fastapi`:

```python
from fastapi import BackgroundTasks
```

    id("gradlebuild.module-identity")
    `maven-publish`
    signing
    `java-gradle-plugin`
    id("com.gradle.plugin-publish")
}

extensions.create<PluginPublishExtension>("pluginPublish", gradlePlugin)

tasks.validatePlugins {
    enableStricterValidation = true
}

// Remove gradleApi() and gradleTestKit() as we want to compile/run against Gradle modules
