Issue Summary

Currently in Bamboo it is not possible to delete a project from the Bamboo GUI until all the plans under it are deleted. So in an ideal scenario it is not possible to have marked_for_deletion for projects is set as True if there are active plans under the project.

Let's assume for some unknown reason if marked_for_deletion for a project is set as True and the project has active plans under it, from Bamboo ( 9.x.x) Bamboo will delete the project and the plans without any checks.

In Bamboo ( 8.x.x ) this check was present and the below error would be seen in the logs

2025-02-04 13:07:43,003 INFO [DelayedDeletionThread] [DeletionServiceHelper] Deleting 1 Project(s) marked for deletion
2025-02-04 13:07:43,004 INFO [DelayedDeletionThread] [DeletionServiceHelper] Deleting BAM
2025-02-04 13:07:43,177 ERROR [DelayedDeletionThread] [DeletionServiceHelper] Project BAM (BAM) contains plans. Delete the plans first.
java.lang.IllegalArgumentException: Project BAM (BAM) contains plans. Delete the plans first.
        at com.google.common.base.Preconditions.checkArgument(Preconditions.java:43

Steps to Reproduce

1) Set marked_for_deletion column as true inside Project table for a project which has active plans under it
2) Wait for the Background deletion service to run.

Expected Results

Warning as per the above should be thrown in the logs

Actual Results

The active plans gets deleted.

Workaround

None as of now.
