• 由于您希望在管道A（P_A）运行不成功时执行它，因此可以使用until循环和标志变量来实现此要求。
• 我已经设置了一个值为false的标志变量。

• 在until内部，我有我的管道A（P_A），如果它失败了，那么我将使用另一个set变量activity并将其值设置为false本身。
• 如果流水线A成功运行，那么我将flag变量value设置为true，从而停止until循环。

• 下面是一个管道JSON结构，您可以将其作为管道B的模板。

您可以为整个需求创建一个主管道
1.创建一个变量并将默认值赋为“False”
1.使用执行管道活动来执行PipelineA。将Waitoncompletion设置为True
1.通过“完成时”（绿色）箭头将其连接到设置变量活动
1.在设置变量活动中将状态变量设置为“True”
1.通过“on completion”路径将其与If Activity连接（蓝色）
1.在If活动中，检查“status”变量是否为true
1.在真正的块中，通过执行管道活动调用管道B
1.在false block中，使用web activity调用rest API再次运行管道A
