With Bamboo 6.7 the "Build Warning Parser" task was introduced.

sadly it does not support yamllint - which would be useful to validate changes on yaml specs by running yamllint against them.

It's also kind of strange that puppet-lint is implemented but yamllint not which is very common to be used in combination.

Alternative to adding only yamllint to the drop down would be to implement BAM-20473 as that would create the possibility to create own parsing patterns.
