No waring/Error for duplicate pipeline name in terraform plan

[jiaquan1]

Describe the bug
when we add a new pipeline, if there is already a ppl with the same name, terraform plan won’t show any warning/error message that the name is taken . It will just fail when terraform apply.

To Reproduce
Steps to reproduce the behavior:

1. Create a new pipeline with terraform module and deploy it;
2. Create a new pipeline with the same name above, and check the terraform plan, everything looks right;
3. terraform apply it, see the error

Expected behavior
A warning or error message in the terraform plan if the pipeline name is already taken.

Hey @jiaquan1

Thanks for raising this, we will look to see what is possible to be able to detect name conflicts of Pipeline Resource during Plans
