# Canceling a Deployment

You can cancel a deployment that’s in progress or queued with the `<sf:cancelDeploy>` task.

:::note
The Ant Migration Tool is retired with Spring ’24. The tool continues to function as-is for future API versions but isn’t updated with new functionality and isn’t supported. If Salesforce adds a new feature that is incompatible with Ant, the Ant Migration Tool won't be updated to support it. To manage metadata changes, switch to Salesforce CLI for a modern, supported developer experience.

The `<sf:cancelDeploy>` task supports these parameters.

| `sessionId`      | Required if `username` and `password` aren’t specified. The ID of an active Salesforce session or the OAuth access token.

Alternatively, use an access token for OAuth authentication.

This example shows a target for canceling a deployment. The value of `requestId` (`sf.​deployRequestId`) is defined in the build.properties file.

```xml
<target name="cancel">
  <sf:cancelDeploy username="${sf.username}" password="${sf.password}" 
      sessionId="${sf.sessionId}" serverurl="${sf.serverurl}" maxPoll="${sf.maxPoll} 
      requestId="${sf.​deployRequestId}"/>
</target>
```

Support for `sf:cancelDeploy` starts with version 34.0 of the Ant Migration Tool.
