lightweight checkout is no longer possible with bitbucket server v7 and merge build strategy, because bitbucket no longer computes a merge commit.

@joaoportela actually that makes perfect sense if you didn’t push any new changes in between. The “Call changes API” only needs to be called once to ensure the refs are created on Bitbucket. This is also what happens if you view the diff in the Bitbucket UI. Once the refs are created the plugin can do its thing (with the heavyweight checkout). What the “Call changes API” does is ensure that Bitbucket for sure created the refs (because with Bitbucket 7 they are only created on demand).
