doesn't implement interface org.flowable.engine.delegate.TaskListener

Hello! It seems like you are encountering an issue related to the Flowable workflow engine. The error message you mentioned indicates that the class you are using does not implement the `TaskListener` interface from the Flowable engine.
To resolve this issue, you need to implement the `TaskListener` interface in your class. The `TaskListener` interface provides callback methods that can be used to listen for task-related events in the Flowable engine.
Here's an example of how you can implement the `TaskListener` interface in your class:
```java
import org.flowable.engine.delegate.TaskListener;
import org.flowable.task.service.delegate.DelegateTask;
public class YourTaskListener implements TaskListener {
@Override
public void notify(DelegateTask delegateTask) {
// Implement your task-related logic here
}
}
```
Make sure to implement the `notify` method, which will be called by the Flowable engine when a task event occurs.
Once you have implemented the `TaskListener` interface, you can register your listener with the Flowable engine to listen for task events. This can be done programmatically or through configuration files, depending on your specific use case.
I hope this helps! Let me know if you have any further questions.
