Task States

The execution states of sequential tasks, concurrent tasks, and action tasks are shown in the diagram below.

• Each task is in the PENDING state after it is created, indicating that it is waiting for execution.
• When a task cannot be executed due to the failure of its predecessor node or the relationship specified by when is not satisfied, it will be set to the SKIPPED state.
• When the task is completed, it will be set to the SUCCESS state if the execution is successful, otherwise, it will be set to the FAILED state.
