Bamboo specs plan branch

[Alfons Ming]

Dear,

I have some problems with bamboo specs.

I have this code for create a plan

.planBranchManagement(new PlanBranchManagement()
.createForPullRequest()
.delete(new BranchCleanup()
        .whenRemovedFromRepositoryAfterDays(7)
        .whenInactiveInRepositoryAfterDays(7))
.notificationLikeParentPlan()
.issueLinkingEnabled(false))

If I try to run this code the first time is ok and I cant create a branch when the properties "When pull is created" but when I try to run another time the code I receive this error:

0:45,677 INFO [BambooServer] An error occurred while publishing plan MP-MCM: Plan branch / workflow: You can't change the default repository because automatic branch management for this plan is dependent on pull requests. Update plan's branching configuration to enable switching the default repository.

I've found this topic with the same problem: https://jira.atlassian.com/browse/BAM-18952 but the solution is not the best way because you have to delete the repository every time you want to run the code ...
