How to get linked issues using JQL / Jira SDK?

[Frederico Betting]

Hi,

I'm building a plugin for Jira and now I have to get linked issues and build some charts with this information. I've tried some different ways to filter issues and the last one that I believe would be the correct one is in the code below:

JqlQueryBuilder builder = JqlQueryBuilder.newBuilder();
builder.where().project(projectId).and().addFunctionCondition("issueFunction", Operator.IN, "hasLinkType", "Blockers");
Query query = builder.buildQuery();

But, for some reason, I still cannot get any response. I have linked issues in my running Jira instance but every time I execute this code I get 0 result.

What's the correct way to get this information using SDK?

Thank you in advance.
