Check if a commit is a merge commit - Bitbucket scriptrunner

[Narasimha Velagaleti]

How do I verify if a commit is a merge commit of a pull request using groovy scriptrunner for bitbucket server?

You just need to check the length of the `parents`. If there are two or more commits, it's a merge commit, otherwise it's a regular commit.

```commit.getParents().size() >= 2```
