DiffRefs not populating for Merge Requests List

[baymac]

For my GitLab Plugin for Jenkins,

I need DiffRefs of Merge Request. Although DiffRefs get populated for single MergeRequest call e.g.

System.out.println(gitLabApi.getMergeRequestApi().getMergeRequest(projectpath, 1));

But it doesn't work when called for a list of Merge Requests. The DiffRefs field is returned null
e.g.

for(final MergeRequest m : gitLabApi.getMergeRequestApi().getMergeRequests("catwoman/gitlab-bs", Constants.MergeRequestState.OPENED)) {
        System.out.println(m);
        System.out.println("-----------------");
    }

For getting the DiffRefs I need to perform an extra api call inside the for loop, e.g.

for(final MergeRequest m : gitLabApi.getMergeRequestApi().getMergeRequests("catwoman/gitlab-bs", Constants.MergeRequestState.OPENED)) {
        System.out.println(gitLabApi.getMergeRequestApi().getMergeRequest(project, m.getIid()));
        System.out.println("-----------------");
    }

Want to know if this has to do something with default GitLab API or gitlab4j?

Thanks.

Unfortunately, the GitLab API does not return diff_refs when fetching lists of merge requests. See
https://docs.gitlab.com/ee/api/merge_requests.html#list-merge-requests
https://docs.gitlab.com/ee/api/merge_requests.html#list-project-merge-requests
https://docs.gitlab.com/ee/api/merge_requests.html#list-group-merge-requests

It only returns diff_refs when fetching a single merge request. see:
https://docs.gitlab.com/ee/api/merge_requests.html#get-single-mr

I do not see any reason for that. Anyway, thanks @gmessner as always. :)

It may be resource intensive to fetch the diff refs, you might think about submitting an issue with GitLab to ask this question. See https://gitlab.com/gitlab-org/gitlab-ce/issues

Okay, I have raised a ticket.
