With the invention of JQL, JIRA search APIs have changed drastically from 3.x versions. Searching in plugins is now done using APIs supporting JQL. In this recipe, we will see how to search for issues within our plugins using those APIs.
For the sake of concentrating on the search APIs, we will look at writing a simple method, getIssues(), that returns a list of issue objects based on some search criteria.
The essence of searching is to build a Query object using JqlQueryBuilder. A Query object will have a where clause and an orderBy clause, which are built using the JqlClauseBuilder class. We can also incorporate conditions in between clauses using ConditionBuilders.
For now, let us assume we want to find all the issues in a particular project (project ID: 10000, key: DEMO) and assign them to the current user within our plugin. The JQL equivalent for this is as follows:
project = "DEMO" AND assignee = currentUser()
The following are the steps to do this...
