可以通过设置参数"trigger_rule"为"all_done"和"one_failed"来解决此问题。"all_done"表示只有在所有上游任务均成功执行后才会触发下游任务，而"one_failed"表示只要有一个上游任务失败或跳过，就会触发下游任务。

示例代码：

from airflow import DAG
from airflow.operators.bash_operator import BashOperator
from airflow.utils.task_group import TaskGroup

default_args = {
    'owner': 'airflow',
    'depends_on_past': False,
    'start_date': datetime(2022, 1, 1),
    'email': ['airflow@example.com'],
    'email_on_failure': False,
    'email_on_retry': False,
    'retries': 1,
    'retry_delay': timedelta(minutes=5),
}

dag = DAG(
    'example_dag',
    default_args=default_args,
    schedule_interval=timedelta(days=1),
)

with TaskGroup('group_a', trigger_rule='all_done', dag=dag) as group_a:
    task_a = BashOperator(
        task_id='task_a',
        bash_command='echo "Task A"',
        dag=dag,
    )

    task_c = BashOperator(
        task_id='task_c',
        bash_command='echo "Task C"',
        dag=dag,
    )

with TaskGroup('group_b', trigger_rule='one_failed', dag=dag) as group_b:
    task_b = BashOperator(
        task_id='task_b',
        bash_command='echo "Task B"',
        dag=dag,
    )

    task_d = BashOperator(
        task_id='task_d',
        bash_command='echo "Task D"',
        dag=dag,
    )

    task_e = BashOperator(
        task_id='task_e',
        bash_command='echo "Task E"',
        dag=dag,
    )

    task_a >> task_b >> [task_c, task_d] >> task_e
